Calculate the Force required to move a stationary object of mass 3kg f – InterviewSolution

InterviewSolution

1.	Calculate the Force required to move a stationary object of mass 3kg from rest to velocity at 8 m/s in 2 seconds
Answer» <p>mass (m) = 3kgInitial Velocity (u) = 0 m/sFinal Velocity (v) = 8 m/sTime (t) = 2 sForce = mass * acceleration Here acceleration(a) = (v-u)/t =(3-0)/2 = 3/2 = 1.5m/s^2Force (F) = ma = 31.5 = 4.5 N</p>
