a 35 kg trunk is dragged 10 m up a ramp inclined at an angle of 12º to the horizontal by a force of 90 N applied at an angle of 20º to the ramp. What is the total work done?
I am supposed to use the W = F*d*cos(angle between force and displacement vectors). My friend says that the angle is 32º, but I think it is supposed to be 20º. Who is right?
