Can a body have zero velocity and still be accelerating?Give example.
Asked by Tanya Singh | 19th Feb, 2012, 10:30: PM
YES! but not permanently ,only momentarily. To explain, say that u throw a ball atvelocity V upwards , the earth's acceleration is -G. consider T=0 at the moment of throwing. V+(-G)T is the velocity of the ball at any instant T (after throwing). At the time T=V/(+G) *we have the ball's velocity 0 but the ball persistently has -G acceleration* all along duration of flight until it hits ground . *Its because the object has (-G) acceleration even at velocity 0 that the ball starts falling and finally comes down to hit the ground.
