Two 5.0-kg carts collide on a one-dimensional air track. The total momentum of the carts was 4.9 kg m/s rightwards before the collision. After the collision, one cart is moving leftwards at 0.15 m/s. what is the velocity of the second cart?

Answers

Answer 1

Answer:

1.13 m/s right

Explanation:

Momentum before = momentum after

p₀ = p

p₀ = m₁ v₁ + m₂ v₂

4.9 kg m/s = (5.0 kg) (-0.15 m/s) + (5.0 kg) v

4.9 kg m/s = -0.75 kg m/s + (5.0 kg) v

5.65 kg m/s = (5.0 kg) v

v = 1.13 m/s

Answer 2

Answer: 1.13 m/s equivalent to 1.1 m/s

Explanation:

Question

A car accelerates at 2.90 m/s . Assuming the car starts from rest , how much time does it need to accelerate to a speed of 23.6 m/s ?

☯[tex] \underbrace{ \sf{Required \: Answer : }}[/tex]

Given :

Initial velocity ( u ) = 0 Final velocity ( v ) = 23.6 m/sAcceleration ( a ) = 2.90 m/s²

To find :

Time ( t )

✎ We know ,

[tex] \boxed{ \underline{ \sf{acceleration \: (a) \: = \frac{final \: velocity \: (v) - initial \: velocity \: (u )}{time \: ( \: t \: )}}}}[/tex]

Substitute the values :

➵ [tex] \sf{2.90 = \frac{23.6 - 0}{t}} [/tex]

➵ [tex] \sf{2.90 = \frac{23.6}{t}} [/tex]

Apply cross product property

➵ [tex] \sf{2.90 \: t \: = 23.6}[/tex]

Divide both sides by 2.90

➵ [tex] \sf{ \frac{2.90 \: t}{2.90} = \frac{23.6}{2.90} }[/tex]

➵ [tex] \sf{t = 8.13 \: seconds}[/tex]

true or false. because the speed of an object can change from one instant to the next, dividing the distance covered by the time of travel gives constant speed​

Answers

true. Because the speed of an object can change from one instant to the next, dividing the total distance covered by the time of travel gives. average speed.

Answer:

False.

Explanation:

Dividing the distance covered by the time would give us the average speed, not a constant speed. Constant speed exists only if the speed of an object does not change.

Heya!!

For calculate force, lets applicate second law of Newton:

                                                    [tex]\boxed{F=ma}[/tex]

                                                 Δ   Being   Δ

                                                 F = Force = ?

                                            m = Mass = 50 kg

                                        a = Aceleration = 7,2 m/s²

⇒ Let's replace according the formula:

[tex]\boxed{F= 50\ kg * 7,2 m/s^{2}}[/tex]

⇒ Resolving

[tex]\boxed{ F = 360\ N}[/tex]

Result:

The force is 360 Netwons.

a 3.5 kg mass has an initial velocity of 4.0 m/s. How much force is required to increase the velocity of the mass to 8.0 m/s in 3.0 seconds?

Answers

Answer:

4.67 N of force are required

Explanation:

The second Newton's law states the net force exerted on a body of mass m that has an acceleration a, is given by:

F=m.a

On the other hand, the kinematics equations relate the acceleration with the change of speed over time, expressed as:

[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]

We are given the initial speed of vo=4 m/s on a mass of m=3.5 Kg, the final speed of vf=8 m/s which took t=3 seconds.

The acceleration is:

[tex]\displaystyle a=\frac{8-4}{3}=1.33[/tex]

[tex]a=1.33\ m/s^2[/tex]

Thus, the force is:

[tex]F=3.5\ Kg\cdot 1.33\ m/s^2[/tex]

[tex]F=4.67\ N[/tex]

4.67 N of force are required
