Problem
A constant-mass slider of mass 2.0kg moves on a horizontal frictionless guide. During the time interval 0≤t≤2.0s a time–dependent horizontal force acts on it, given by F(t)=3t2N. There is no horizontal force on the slider before t=0 or after t=2.0s. Its initial velocity at t=0 is 4.0m s−1 in the direction of the force.
(i) Calculate the impulse delivered to the slider during the interval of action.
(ii) Hence determine the velocity of the slider at t=2.0s.
