When you drop a ball it accelerates downward at a rate of g. if you instead throw it downward, then its acceleration immediately after leaving your hand, assuming no air resistance, is

cannot say, unless the speed of "throw" is given
g
zero
less than g
more than g

Abaseball has a mass of 0.145 kg and approaches a bat at 40.0 m/s. after it is hit, the ball leaves the bat at 50.0 m/s directly back. find the impulse of the bat on the ball. 7.25 kg*m/s 13.1 kg*m/s 5.80 kg*m/s 1.45 kg*m/s

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

A1,700kg car is being used to give a 1,400kg car a push start by exerting a force of 140n the impulse on the smaller car during the 30.0s of contact is +670kg*m/s. what is the impulse of the smaller car on the larger car? -814 kg*m/s 0kg *m/s -670kg*m/s -550kg*m/s
