Answer:10 m/s
Explanation:
For a perfectly elastic collision, coefficient of restitution is e=1.
Let u and v be the velocities of 10 kg and 1 g masses after collision.
Thus, e=
rel. vel. of approach
rel. vel.of separation
=
5−0
v−u
=
5
v−u
But, as e=1, we have v−u=5.
Total momentum before collision is P=10×5=50 kg m/s
Total momentum after collision is P=10×(v−5)+0.001×v=10.001v−50
Thus, 10.001v−50=50⇒v=
10.001
100
≈10 m/s
