A ball is moving with speed 20 m/s collides with a smooth surface as shown in figure. the magnitude of change in velocity of the ball will be
1) 10root3 m /s
2) 20root m/s
3) 40/root3 m/s
4) 40 m/s
Dear student,
Initial velocity,
Final velocity,
Change in velocity = Final velocity - Initial velocity
Regards
Initial velocity,
Final velocity,
Change in velocity = Final velocity - Initial velocity
