During a hockey game, the puck slid from the center line directly to the goal line in 1.5 seconds. The center line is 27 meters from the goal line. As the puck slid, it was chased by a hockey player skating at 9.5 meters per second. What was the puck's velocity?

Answers

Answer 1

Answer: The pucks velocity was 18 meters per second.

Explanation: First I divided 27 by 3 because of the 1.5 seconds and the i multiplied my answer by 2 and got that it traveled 18 meters in 1 second.

Answer 2

During a hockey game, the puck slid from the center line directly to the goal line in 1.5 seconds. The center line is 27 meters from the goal line. As the puck slid, it was chased by a hockey player skating at 9.5 meters per second. And the puck's velocity is 18 m/s.

What is Average velocity?

Average velocity can be defined as the average rate of change of displacement with respect to time. Average velocity is a measure for distance traveled in a given time.

We can calculate the average velocity by the rule

v = s/t (m/s)

where s is the displacement and t is the time

Mathematically,

speed = distance/ time

The puck traveled a distance of 27 m in 1.5 seconds

The speed of the puck is thus;

27/1.5 = 18 m/s

Thus, the puck's velocity can be calculated as 18 m/s.

A ball of mass 100g thrown by a man moves at a velocity of 100m/s. what is the momentum? need the answer step by step plssss!! i need it fast!!!!!!!

Answers

Explanation:

Mass of the ball= 100 g = 0.1 kg

Velocity of the ball before collision=10 m/s

Momentum of the ball before collision, p(i)=mv= 0.1×10=1 kgm/s

Since, ball returns back with same velocity

Therefore, velocity of ball after collision = -10 m/s (-ve sign due to opposite direction)

So, momentum of ball after collision,p(f) = 0.1 ×(-10) = -1 kgm/s

Now, Impulse generated in the ball= change in momentum= p(f)-p(i)= -1–1= -2 kgm/s

What is soil erosion

Answers

Answer:

Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage.

Answer:

It is the breakdown of soil due to natural processes

Explanation:

Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide

Explanation:

Cara is swimming in a river. She can swim downstream up to a maximum speed of 66 meters per-minute. If she is swimming downstream at half of her maximum speed, how far will she swim in 13 minutes?

Answers

It would be 429 because in the question it said “ if she was swimming downstream of HALF of her maximum speed, how far will she swim for 13 minutes” so first you would divide 66 by 2 and get 33 then you would multiply 33 by 13 to get you’re answer.

429 meters
Half of 66 is 33 so that’s half of her maximum speed.
You then take 33 and times it by 13.
66/2=33
33x13=429
