Question 104

H

A student pulls a block at constant speed along a bench using a horizontal force of 4.0 N. A point on the block moves from the 15 cm mark to the 90 cm mark of a ruler. The student calculates the work done as $J4.0\times90=360\ \mathrm{J}$ . By what factor is this larger than the correct value?
