Impulse-Momentum with a Time-Dependent Force and Kinetic Friction
Engineering Mechanics Dynamics · Engineering Mechanics — Dynamics: Newton's Second Law / Work–Energy Method
A 10-lb block has a speed of 4 ft/s when a horizontal force $F = 8t^2$ lb is applied. Determine the velocity of the block when it has moved $s = 30$ ft. The coefficient of kinetic friction is $\mu_k = 0.2$.
