I think the answer is "<span>The ball that went out of the park shows more work because the distance was greater."</span>
When an object is dropped, tossed, or kicked, as long as it is not laying on the ground, it accelerates downward, because of the force of gravity acting on it.
Only some metals are attracted by magnets; these metals are called ferromagnetic is your answer
Potential energy and work done are the same thing as much as kinetic energy and work done are the same thing. Potential energy is a state of the system, a way of storing energy as of virtue of its configuration or motion, while work done in most cases is a way of chaning this energy from one body to another.
Explanation:
(a) According to the law of conservation of energy,
Potential energy = Kinetic energy
mgh =
Putting the given values into the above formula as follows.
mgh =
h = 0.9 m
Therefore, the height H is 0.9 m.
(b) For the given situation,
Kinetic energy = work done by friction
u = 0.3
Thus, we can conclude that the coefficient of kinetic friction on the horizontal surface is 0.3.
