Question

A ball of mass 600 grams strikes a wall with a velocity of 5m/s at an angle 30 degree with the wall and rebounds with the same speed at the same angle with the wall. the change in momentum of the ball is

A
3kgms1
B
1kgms1
C
0.25kgms1
D
zero
Solution
Verified by Toppr

The correct option is A 3kgms1
Mass=0.6kg
velocity=5m/s
change of momentum =3kgm/s
Hence,
option (A) is correct answer.
