A block of mass m1 = 1.70 kg slides left to right at v1 = 5.20 m/s towards a second block with mass m2 = 3.95 kg sliding right to left at v2 = 3.10 m/s on a frictionless surface.

(a) What is the momentum (magnitude and direction) of each mass before they

collide? Note there are two quantities asked for in this part.

(b) When the two masses collide, they stick together in a perfectly inelastic collision. What is the velocity (magnitude and direction) of the combined masses?

(c) What is the impulse block m1 exerts on block m2 during the collision? (d) If the time of the collision is 0.100 s, what is the average force block m1 exerts on

block m2 during the collision?
