1.A 0.75kg mass moving with a velocity of v1=1.2 ^i−3.4^j m/s , strikes a 2.4kg mass moving

with a velocity of v2=0.58^jm/s . Assume the collision is inelastic.

a. Calculate the speed of the combined mass after the collision.

b. Calcualte the angle (relative to the x axis ) of the trajectory of the combined mass after

the collision

2.A 60N bowling ball is lifted 1.5m off of the ground, and held at rest.

a.Determine the bowling ball's momentum.
