Atennis ball, a bowling ball, and a feather are dropped from the top of a tall building at the same time. consider what you have learned about air resistance. which object reaches the ground first?

A0.5-kg object is connected to a spring that undergoes oscillatory motion. there is friction between the object and the surface it is kept on given by coefficient of friction μk = 0.06 . if the object is released 0.2 m from equilibrium, what is the distance that the object travels? given that the force constant of the spring is 50 n m-1 and the frictional force between the objects is 0.294 n.
