Question

A pendulum bob A (0.5 kg) is given an initial
speed of vA = 4 m/s when the chord is
horizontal. It then hits a stationary block B (1
kg) which then slides to a maximum distance
d before it stops. Determine the value of d.
The coefficient of static friction between the
block and the plane is μk = 0.2. The coefficient
of restitution between A and B is e = 0.8.
Ans: d=1.0034 m
