suppose the cart has mass m = 203 g, and it strikes the clay at speed vo = 5.24 m/s and comes to a dead stop. Assume the track is frictionless, and the clay is crushed inward by 1.83 cm.
a)Find the magnitude of the impulse exerted by the clay on the cart.
1 N-m i got this answer 1.06372 but couldn't get paerts b and c
b) Find the magnitude of the average force exerted by the clay on the cart.
HINT: Use kinematics, assuming the force is constant during the impulse!
c) Find the time it took for the cart to come to rest while in contact with the clay.
