At what point in the swing of a pendulum is the maximum amount of the ball's motion transferred to the object it hits? (I think it's at its lowest swing point but I'm not completely sure.) And what does this "kinetic energy" depend on?
a body moving with a uniform acceleration cover 65ft in 5th second and 105ft in 9th second.Find the distance it will move in 20second.
