A metal ball (B1) has a velocity of 30 m/s at 50° NorthEast. A rubber ball (B2) has a velocity of 20 m/s at 15° NorthEast. They collide, bouncing off each other.  B1 has a velocity of 24.6 m/s at 47° NorthEast the instant after they collide Assume: B1 has a mass of 20 kg B2 has a mass of 5 kg Their velocities remain constant until the collision All velocities are

Two vehicles approach a right angle intersection and then collide. After the collision, they become entangled. If their mass ratios were 1:4 and their respective speeds as they approached were both 13 m/s, find the magnitude and direction of the final velocity of the wreck. 12.5 m/s at 79° 13.1 m/s at 79° 15.7 m/s at 79° 16.3 m/s at 79° Correct.

A ball of mass 2.00-kg is traveling in the positive x-direction at 10.0 m/s and obliquely collides with a 3.00-kg ball that was initially at rest. After the collision, the 2.00-kg ball is traveling at 30.0° above the positive x-axis, while the 3.00-kg ball has a speed of 4.00 m/s. Determine the direction the 3.00-kg ball is moving relative to the positive x direction, and the speed of the 2.00-kg ball.

Solved Problem: You've just been involved in an accident in which the damage is significant but none is hurt. While driving east through an intersection you are broadsided by a large sport utility vehicle travelling north. What speed and direction do the two vehicles move off with just after the collision. Assume that the collision is perfectly inelastic. Question: Determine the velocity of the two just after the collision. Known: m, = 1000 kg, m, = 2000 kg. V = 10 m/s and V = 20 m/s. Principle: Conservation of Momentum in 2D Approach: Determine initial and final momenta and solve for velocity ?
