[QUOTE="Enigman, post: 4494097, member: 481884"] You can't 'overpower' Kinetic Energy; whatever you may mean by it... You can absorb K.E. You can give it more K.E. Overpower, mmm..nope. The change in direction of velocity relates to change in momentum. Force is rate of change of momentum wrt time. With given information you can at best calculate change in momentum. Also as others have mentioned the ball won't stop after 20m. Have you been given air resistance, or the height at which ball is at? And it may that by 20m you really mean 20m/s? [/QUOTE]
