On a day with no wind, a large object is dropped from a tall building. The object experiences air resistance during its fall to the ground. State and explain, in terms of the forces acting, how the acceleration of the object varies during its fall.

As the object is released two forces act on it.Its weight and and air resistance. At this point its weight is much greater due to the force of gravity on the object so it accelerates downward. As its s...

What is the mass of an object travelling at 15 m/s with a kinetic energy of 100 J?

Kinetic Energy (E_k) = 1/2(mv²).This can be rearranged such that, m = (2E_k)/v²we know from the question that E_k= 100 J and we know that v = 15 m/sso ...
