(Answered) 1 a small 100 g cart is moving at 170 mson an air track

Academics

1= A small, 100 g cart is moving at 1.70 m/son an air track when it collides with a larger, 1.00 kg cart at rest. After the collision, the small cart recoils at 0.860 m/s.

What is the speed of the large cart after the collision?

2= A kid at the junior high cafeteria wants to propel an empty milk carton along a lunch table by hitting it with a 2.9 g spit ball.

If he wants the speed of the 30 g carton just after the spit ball hits it to be 0.29 m/s , at what speed should his 2.9 g spit ball hit the carton?
