A body of mass 0.5 kg is moving with a velocity of 2m/s. When a constant force of x newton acts on its fro 2s, its velocity becomes 3m/s. What is the value of x?

A

1N

B

5N

C

0.5N

D

0.25N

Text Solution

Verified by Experts

The correct Answer is:
D
`F= (m(v-u))/(t)= (0.5xx(3-2))/(2)=0.25N`
`therefore x=F=0.25N`
