A man pushes a 143 kg crate a distance of d= 5 m upward along a frictionless slope that makes an angle of 0=30 with the horizontal. The force he exerts is parallel to the inclined plane. If the crate accelerates up the slope at 2.2 m/s, what is the work done by the man, in Joules? Take g = 9.8 m/sz. Please round your answer to the nearest whole number (integer)
