Question details

1. (10 points) The crate has a mass of 150 kg and rests on a surface for which the coefficients of static and kinetic friction are and 0.2, respectively. If the motor M supplies a cable force of F (8t2 20) [N], where t is in seconds, determine the power output developed by the motor when t 5 s. Hint: First determine the time needed for the force to cause motion. (Use 9.81 m/s2)
Final answer should be
