Question

A rare and valuable antique chest is being moved into a truck using 5.00m long ramp. The weight of the chest plus packing material is 1200N. Ifthe truck bed is 1.00m above the ground, find the work done by the movesrs as they slide the chest up the ramp if the coefficient of friction between the chest and the ramp is 0.200. =____kJ

Explanation / Answer

Work Done = Force * Displacement = 5*Force Sin(teta) = 1/5 =>Teta = 11.53695903 Degrees Force = m*a = (1200*sin(radians(11.53695903)))+(0.2*1200*cos(Radians(11.53695903))) = 475.1510153 N Therefore work done = 5*Force = 2375.755076 J
