1.If the force exerted on cable AB by the motor is F =(100^3/2) N, where t is in seconds, determine the 50-kg crates velocity when t = 5s. The coefficents of static and kinetic friction between the crate and the ground are u(s) =.4 and u(k) = .3 respectively. Initially the crate is at rest.

2.If a cylinder of A-36 steel 1 foot long with a diameter of 1 inch is wedged tightly between two immovable isothermal walls and the cylinder is heated from RTt to 300 c what will happen?describe, do not use an equation
