A rock with a mass of 100 g rests on a frictionless, horizontal surface. A bullet with mass 6.00 g is travelling due east at 326 m/s toward the rock. The bullet collides with the rock. After the collision the bullet moves due south at a speed of 250 m/s, and the rock moves in a different direction. In this problem, assume that the positive x axis points east and the positive y axis points north. What direction does the rock move in after the collision? Give your answer as an angle in degrees relative to the positive x axis. Your answer should have 2 decimal places. A rock with a mass of 100 g rests on a frictionless, horizontal surface.
