A student could either pull or push, at an angle of 300⁰ from the horizontal, a 60 kgkg crate on a horizontal surface, where the coefficient of kinetic friction between the crate and surface is 0.21. The crate is to be moved a horizontal distance of 25 mm A) Compared with pushing, pulling requires the student to do more, less, or the same work. B) Calculate the minimum work required for both pulling and pushing. Express your answers using two significant figures separated by a comma. Answer must be in J Wpulling, Wpushing =
