1. You throw a 0.145-kg baseball straight up, giving it an initial velocity of magnitude 20.0 m/s. a) Find how high it goes, ignoring. resistance. II. Suppose your hand moves upward by 0.50m while you are throwing the ball. The ball leaves your hand with an upward velocity of 20.0 m/s. a) Find the magnitude of the force (assumed constant) that your hand exerts on the ball. b) Find the speed of the ball at a point 15.0m above the point where it leaves your hand. Ignore air resistance. 1. You throw a 0.145-kg baseball straight up, giving it an initial velocity of magnitude 20.0 m/s. a) Find how high it goes, ignoring. resistance. II.
