As the collision is elastic,  u₁ + u₂ = v₁ + v₂ must be satisfied.

According to the law of momentum conservation, momentum is never created nor destroyed inside a problem domain.

Before collision,

velocity of body A = u₁ velocity of body B = u₂

After collision,

velocity of body A = v₁ velocity of body B = v₂

Hence, according to  law of momentum conservation

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

As the collision is elastic, total kinetic energy is also conserved.

1/2m₁u₁² + 1/2m₂u₂² = 1/2m₁v₁² + 1/2m₂v₂²

This two equation satisfy that:

The normal stress is 1292.5 Pa and the shear stress is 330 Pa on the plane at an angle of 50° relative to the principal stress axes.

Shear stress is described as the component of stress coplanar with a material cross section which arises from the shear force, the component of force vector parallel to the material cross section.

We will calculate the major and minor principal stresses:

σ1 = (ob + ja) / 2 + (ja - ob) / 2 * cos(2b)

σ2 = (ob + ja) / 2 - (ja - ob) / 2 * cos(2b)

The normal stress on the plane at angle b can be calculated as:

σ = (σ1 + σ2) / 2 + (σ1 - σ2) / 2 * cos(2b)

The shear stress on the plane at angle b can be calculated as:

τ = (σ1 - σ2) / 2 * sin(2b)

Applying the  formulas, we have:

σ1 = (500 + 1500) / 2 + (1500 - 500) / 2 * cos(2 * 50) = 1000 + 500 * 0.87 = 1000 + 435 = 1435 Pa

σ2 = (500 + 1500) / 2 - (1500 - 500) / 2 * cos(2 * 50) = 1000 - 500 * 0.87 = 1000 - 435 = 565 Pa

σ = (1435 + 565) / 2 + (1435 - 565) / 2 * cos(2 * 50) = 1000 + 435 * cos(100) = 1000 + 292.5 = 1292.5 Pa

τ = (1435 - 565) / 2 * sin(2 * 50) = 435 * sin(100) = 435 * 0.76 = 330 Pa

Heating effects impact the flow of the electricity.

Explanation:

The definition of the terms will be:

(i) Fluid: A fluid is a substance that continuously deforms (flows) under an applied shear stress. Examples of fluids include liquids and gases.

(ii) Viscosity: Viscosity is a measure of a fluid's resistance to flow. It is defined as the ratio of shear stress to the rate of strain in the fluid.

(iii) Drag Force: Drag force is a force acting on a moving object in a fluid that opposes its motion. It is proportional to the velocity squared of the object and the fluid density.

(i) Fluid Mechanics: Fluid mechanics is the branch of physics that deals with the study of the behavior of fluids at rest and in motion. It covers various topics such as fluid statics, kinematics, and dynamics.

(ii) Fluid Statistics: Fluid statistics deals with the behavior of fluids in terms of the statistical distribution of their properties, such as temperature, pressure, and velocity.

(iii) Fluid Kinematics: Fluid kinematics is the study of fluid motion without considering the forces that cause the motion.

(iv) Fluid Dynamics: Fluid dynamics is the study of fluid motion and the forces that cause the motion. It covers topics such as the conservation of mass, momentum, and energy, and the study of fluid flows, such as laminar and turbulent flows.

(i) Circular Motion: Circular motion is motion in which an object moves along a circular path with a constant speed.

(ii) Rotational Motion: Rotational motion is motion in which an object rotates about a fixed axis.

(iii) v = wr: This equation states that the velocity of a point on a rotating object is equal to the product of its radial distance (r) from the axis of rotation and the angular velocity (w) of the object.

(iv) a = ar: This equation states that the radial acceleration of a point on a rotating object is equal to the product of its radial distance (r) from the axis of rotation and the angular acceleration (a) of the object.

(v) Torque: Torque is the rotational equivalent of force. It is defined as the cross product of the radial distance (r) and the force (F) applied to an object. The mathematical expression of torque is given by τ = r x F, where τ is the torque, r is the radial distance, and F is the force.

Projectile motion is the motion of an object that is projected into the air and then is subject to the force of gravity. To calculate the range (R), time of flight (T), and maximum height (H) of a projectile, the following equations can be used:

R = v0x * T, where v0x is the initial velocity in the x direction and T is the time of flight.

T = 2v0y / g, where v0y is the initial velocity in the y direction and g is the acceleration due to gravity.

H = v0y^2 / (2g), where v0y is the initial velocity in the y direction and g is the acceleration due to gravity.

Bernoulli's equation is a principle that relates pressure and velocity in a fluid system. It states that the pressure of a fluid decreases as its velocity increases. The expression of Bernoulli's equation is given by P + 1/2 ρv^2 + ρgy = constant, where P is the pressure, ρ is the fluid density, v is the fluid velocity, g is the acceleration due to gravity, and y is the height

The velocity of the balls if the collision is perfectly elastic is -0.78 m/s and v₂ = 1.98 m/s.

A state where there is no net loss in the kinetic energy in the system of two objects as the result of the collision is called as an elastic collision.

Inelastic collisions is a type of collision where there is a loss of kinetic energy.

Using the law of conservation of momentum:

m₁u₁ + m₂u₂ = m₁v₁ + m₂ v₂ (u₂ = 0)

5 x 2 = 5v₁ + 7v₂

10 = 5v₁ + 7v₂

v₂ = (10 - 5v₁)/7

Elastic collision so kinetic energy conserved:

1/2 x 5 x (2)²  = 1/2 (5v₁² + 7v₂²)

20 = 5v₁² + 7((10 - 5v₁)/7)²

140 = 35v₁² + 5v₁² + 100 - 20v₁

40v₁² - 20v₁ - 40 = 0

v₁ = -0.78 m/s

The first ball is lighter so its velocity will change direction due to collision.
