The coefficients of static friction and kinetic friction are µ, = 0.3 and 4, = 0.2, respectively, between the crate and the surface. The motor is towing the 1000 kg crate and rests on the flat surface. It delivers an increasing horizontal pulling force of T = 500 t5² Newton, where t is in second, to its cable at A, after which the force is kept constant at 5000 N. Determine the velocity (m/s) of the crate when tą = 5 s.
