Answer:
Explanation:
The initial kinetic energy will be increased by the loss of potential energy and be decreased by the work of friction.
½mv₁² = ½mv₀² + mgh - Fd
½70v₁² = ½(70)14² + 70(9.8)(30) - 13(440)
v₁ = 24.9112... ≈ 25 m/s
Answer:
ok
Explanation:
what is the length of the court. you need the length to answer the question
I disagree since friction will cause the ultimate height to be lower than what was anticipated. To reduce the height, resist the action.

What is the height?</h3>
The vertical distance between an object's top and the bottom is defined as its height.
It is measured in centimeters, inches, meters, and other units. The height of the cliff is obtained by the Newton equation of motion.
My actual height was less than what I had anticipated. this is because the puck's movement along the track was impeded by friction.
To the Khalida, I object. Disagree, since friction will cause the ultimate height to be lower than the anticipated height. To reduce the height, resist the action.
Hence, I disagree with Khalida.

Okay. If a car takes 2 hours to go 80 miles, the car is going 40 miles an hour. All you have to do is 80/2 in order to get your answer, because you do distance divided by time to find the speed.
Answer:
The second arrow from the top to the bottom
Explanation:
This can be explained by the Newton's third law.
For every action there is an equal and opposite reaction.
When an object A exert a force to an object B. Then object B also excerts a force with the same size but opposite direction to object A.
