Question

The velocity-time graph of hard ball of mass 100 gram moving along a straight line concrete track is given below calculate the acceleration and the force exerted by the track to bring the ball at rest.
​

Answer 1

15.620499351-acceleration

Explanation:

slope of v-t graph gives acceleration which is =hypotneous

P*P+B*B=H*H

12*12+10*10=H*H

144+100=244

H=√244=15.620499351
