Question

two balls are moving along a frictionless table and collide. ball 1 has a mass of 0.6 kg and ball 2 has a mass of 0.4 kg. before the collision, ball 1 is moving with a speed of 6.5 m/s at an angle of 38 degrees below the horizontal, and ball 2 is moving with a speed of 4.2 m/s at an angle of 53 degrees above the horizontal. air resistance is negligible. if the collision is completly inelastic...

a) what is the total KE of the system before the collision?

b) what is the final speed of ball 1?

c) what are the final speed and direction of ball 2?

d) what is the total KE of the system after the collision?

please include detailed steps and equations used, thanks! i want to know how to do it, not just the answer.

Explanation / Answer

M? = 0.6 kg

V? = 6.5 m/s

?? = -38
