A constant force acting on a body of mas...

A constant force acting on a body of mass 3.0 kg changes its speed from `2.0 m s^(-1)` to `3.5 m s^(-1)` in 25 s. The direction of the motion of the body remains unchanged. What is the magnitude and direction of the force ?

Text Solution

Verified by Experts

`a = 1.5 //25 = 0.06 ms^(-2)`
`F = 3 xx 0.06 = 0.18 N` in the direction of motion .
