ation! A motor is used to pull a crate horizontally across the ground at a constant speed of 1.7 m/s using a tension (in the cable) of 120 N. The crate weighs 850 N. (a) What is the net force on the crate in this situation? (b) What must the force of friction and coefficient of friction be while the crate is moving in this situation? (c) How much work does the motor do for every 10 meters the crate is moved? (d) What must the minimum power of the motor be to maintain this speed of 1.7 m/s?
