A body of mass 25kg changes its speed from 15m/s to 35m/s in 5 seconds by the action of an applied force F. Find the value of F.

A.

100N

B.

375N

C.

500N

D.

600N

Correct answer is A

F=ma=m(vut)

F=25(35155)=25×4=100N

A force of 200N acting on a body of mass 20kg initially at rest causes it to move a distance of 320m along a straight line for t secs. Find the value of t.

A.

4s

B.

6s

C.

8s

D.

10s

Correct answer is C

F = ma

200=20aa=10m/s2

s=ut+12at2

320=(0×t)+1210t2

320=5t2t2=64

t=8secs
