A ball hits a vertical wall horizontally at bounces back at |
|
a) |
There is no acceleration because |
b) |
There may be an acceleration because its initial direction is horizontal |
c) |
There is an acceleration because there is a momentum change |
d) |
Even though there is no change in momentum there is a change in direction. Hence it has an acceleration |

c) |
There is an acceleration because there is a momentum change |
d) |
Even though there is no change in momentum there is a change in direction. Hence it has an acceleration |
(c) As the ball bounces back with same speed so change in momentum And we know that force = rate of change of momentum force will act on the ball so there is an acceleration |
