Question

A force acts for 10s on a stationary object of mass 100kg after which force cease to act. The body moves to a distance of 100m in the next 5s. Calculate:-
1) The velocity acquired by the object
2) The acceleration produced by the force
3) Magnitude of force ​

Answer 2

Answer:

say initial velocity is 0

then, v=u+at

v= 0+ a10

v=10a

After 10s body starts moving and cover 100m in 5s

S= vt

100= (10a) 5

a=2m/s2

using the value of a in F=ma

F=100x2=200N

and v=10a =10 x 2= 20m/s
