Question 4
Boxes with mass of 1 kg and 2 kg, made of the same material, are given the same brief push and they slide along the cement floor. They move and come to stop due to friction. Complete the following statements by filling in the blank with the greater symbol (>), smaller symbol (<) or equal symbol (=). (a) Just after the brief push, the velocity of 1 kg box is … that of 2 kg box. (0.5 point) (b) Just after the brief push, the kinetic energy of 1 kg box is … that of 2 kg box. (0.5 point) (c) The frictional force on 1 kg box is … that of 2 kg box. (0.5 point) (d) The displacement of 1 kg box is … that of 2 kg box. (0.5 point)
