A 0.050-kg lump of clay moving horizontally at 12m/s strikes and sticks to a stationary 0.1-kg cart that can move one a frictionless air track. Determine the speed of the cart and clay after the collision.

a) What is the impulse of the clay? (-0.4 Ns)

b) What is the average force of the clay if the collision time is 0.6ms? (-667N)

c) What is the impulse of the cart? (+0.4 Ns)

d) What is the average force of the clay? (667N)
