On an ice rink a 3 kg object initially moving a speed of 5, Ask an Expert

Academics

On an ice rink, a 3 kg object initially moving a speed of 5 m/s, strikes a 6 kg object initially at rest. Afterwards, the first object moves off with a speed of 2.75 m/s in a direction 80 degreesfrom its original direction of motion.

a) what is the velocity of the second object after the collision?

b) what is the change inenergy during the collision?
