A 320 Kg rock, beginning from rest, slides down a 3 m frictionless ramp that makes a 25° with the
horizontal. The rock hits a stationary cart, m =100 kg, and begins to roll.
A: Use the Newtons laws to determine the speed of the rock at the bottom of the ramp
B: Assume the rock collides with the cart completely ineleastically. What is the speed of the rock-cart
system after the collision.
C: If the collision between the rock and the cart is 0.8 sec. what was the force the cart exerted on the
rock-magnetude and direction.
