Question

The velocity time graph of a ball of mass 20g moving along a straight line on a table is given in fig. How much force does the table exert on the ball to bring it to rest ?​

Answer 1

Answer:

velocity given= 20 cm s-1

time= 10sec

velocity in 0.2 m s-1

acceleration = .2/ 10

0.02 ms-2

force = mg

mass = 20g= 0.02 kg

0.02× 0.02

0.0004 N
