A 500-g block traveling at 60 cm/s slides onto a 1-kg cart as shown. The block stops sliding before reaching the end of the cart.
   
 
   
   As the block is sliding on the cart,
   which object has the larger net
   force on it?

  1.the cart
  2.the block
  3.neither; the net force is the same
  4.impossible to determine

Question 2

Cart A with momentum p (in magnitude) and speed 2v collides with cart B at rest. After the collision, cart A has speed v and cart B has speed 3v, as shown. What can you say about the momentum of cart B after the collision?
 
  1.It is smaller than p.
  2.It is equal to p.
  3.It is larger than p.
  4.It is impossible to predict what the momentum of cart B will be after the collision.
