If the force exerted on cable AB by the motor is F= (100 t/2) N, where t is in seconds, determine the 55-kg crate's velocity when t=6s. The coefficients of static and kinetic friction between the crate and the ground are = 0.38 and 0.30, respectively. Initially the crate is at rest. (Figure 1). Express your answer to three significant figures and include the appropriate units.
