here,
mass of puck A , mA = 0.25 kg
mass of puck B, mB = 0.374 kg
final velocity of A , vA = 0.125 m/s
final velocity of B , vB = 0.649 m/s
a)
let the speed of the particle before the collison be uA
using conservation of momentum
mA * uA = mA * vA + mB * vB
0.25 * uA = 0.25 * 0.125 + 0.374 * 0.649
uA = 0.846 m/s
b)
the change in total kinetic energy of the system , KE = KEf - KEi
KE = (0.5 * mA * vA^2 + 0.5 * mB * vB^2) - (0.5 * mA * uA^2)
KE = 0.5 * ( 0.25 * 0.125^2 + 0.374 * 0.649^2 - 0.25 * 0.846^2) J
KE = - 8.75 * 10^-3 J
