On a frictionless, horizontal air table, puck A (with mass 0.250 kg) is moving toward puck B (with mass 0.300 kg), which is initially at rest. After the collision, puck A has a velocity of 0.150 m/s to the left, and puck B has a velocity of 0.640 m/s to the right. What was the speed of puck A before the collision?

Answer #1

mass of puck A m1 =0.250 kg , m2 = 0.3 kg ,

intial velocity of puck A    u1 =?

u2 =0

after collisoin v1 = -0.150 m/s (left), v2 = +0.640 kg

from conservation of momentum

m1u1 + m2u2 =m1v1+m2v2

m1u1 = 0.1545

u1 = 0.618 m/s towards right
