Point B moves relative to point A according to the below equation: v B / A = ( 3 i ^ + 2 j ^ )  m/s {“version”:”1.1″,”math”:”v_{B/A}=\left(3\widehat{i}+2\widehat{j}\right)\text{ m/s}”} Point A moves with an absolute velocity according to the below equation: v A = ( 4 i ^ − 1 j ^ )  m/s {“version”:”1.1″,”math”:”v_{A}=\left(4\widehat{i}-1\widehat{j}\right)\text{ m/s}”} Determine the absolute velocity of point B (give your answer in vector form).

A motor pulls a 50‑kg crate up an s = 6 m ramp inclined at 20° at a constant velocity of v = 1 m/s. The motor is supplied a constant power of 300 W. The coefficient of kinetic friction is 0.20.    (10 points) Determine the work done by the motor to get the box from the bottom to the top of the ramp. _______ N-m b. (10 points) Determine the efficiency of the process. _______ %
