A body of 5kg is moving with a velocity ...

A body of 5kg is moving with a velocity of 20m/s. If a force of 100N is applied on it for 10 s in the same direction as its velocity, what will now be the velocity of the body?

A

200 m/s

B

220 m/s

C

240 m/s

D

260 m/s

Text Solution

Verified by Experts

The correct Answer is:
B
`F = mxxa rArr a = 100/5 = 20 m//s^2`
`v = u + at = 20 + 20 xx10 = 220 m//s`
