FI 3-2. If motor M exerts a force of F = (lOr + 100) N on
Chapter 13, Problem F13-2(choose chapter or problem)
If motor M exerts a force of \(F=\left(10 t^{2}+100\right) \mathrm{N}\) on the cable, where t is in seconds, determine the velocity of the 25-kg crate when t = 4 s. The coefficients of static and kinetic friction between the crate and the plane are \(\mu_{s}=0.3 \text { and } \mu_{k}=0.25\), respectively.The crate is initially at rest.
