A hydrogen atom (m = 1.674 x 10-27 kg) is moving witha velocity of 1.1250 x 107 m/s. It collides elastically witha helium atom (m= 6.646 x 10-27 kg) at rest. After thecollision, the hydrogen atom is found to be moving witha velocity of -6.724 × 106 m/s (in a direction opposite toits original motion). Find the velocity of the helium atomafter the collision in two different ways: (a) by applyingconservation of momentum; (b) by applying conservationof energy.

One billiard ball (mass 118 grams) is moving due east at 5.0 m/s. A tennis ball (mass 321 grams) is moving due west at 4.0 m/s. The two balls have a glancing blow, which means they do not bounce along the same line as their original motion, but rather, deflect at an angle to their original paths. You measure the billard ball's motion as it moves 26.0° north of east, and you measure that the tennis ball is travelling 19.0° south of west. What is the speed of the billiard ball after the collision? Your Answer: Answer

An unstable nucleus of mass 1.7 ✕ 10−26 kg, initially at rest at the origin of a coordinate system, disintegrates into three particles. One particle, having a mass of m1 = 1.8 ✕ 10−27 kg,moves in the positive y-direction with speed v1 = 5.4 ✕ 106 m/s. Another particle, of mass m2 = 9.0 ✕ 10−27 kg, moves in the positive x-direction with speed v2 = 3.2 ✕ 106 m/s. Find the magnitude and direction of the velocity of the third particle. Answer the following:
Two masses undergo a collision and they stick together. M1 has a mass of 550g and was traveling at an unknown velocity toward the second mass, M2=400g, which was traveling in the same direction at 4.5m/s. After the collision, they have a velocity of 5.1 m/s. Determine the velocity of the first mass before the collision.
