Joey has a mass of 50 kg and he is standing at rest on the friction-less ice. His partner tosses him a ball with a mass of 10 kg and a speed of 6 m/s. Joey catches the ball firmly and he slides backward on the ice with a speed of Which below? 4 m/s 1 m/s 6 m/s

A crane drops a 1.9 kg steel ball onto a steel plate. The ball's speeds just before impact and after are -8.4 m/s and 3.2 m/s, respectively. If the ball is in contact with the plate for 0.041 seconds, what average force does the ball exert on the plate during impact?

2.5 m/s A 50.0-kg boy runs at a speed of 10.0 m/s and jumps onto a cart as shown in the figure. The cart is initially at rest. If the speed of the cart with the boy on it is 2.50 m/s, what is the mass of the cart? 10 m/s v = 0 A) 150 kg B 175 kg c) 260 kg D 210 kg

Create a perfectly inelastic collision where two objects collide and get stuck together. After the collision, the two objects will travel at a speed of 30 km/h and in the direction of W 30˚ S, as shown in the picture. You have control of each of the following variables: The mass of the first object The mass of the second object The speed of the first object The speed of the second object The direction of the first object The direction of the second object
