(a)[2]
State and explain how the kinetic energy of the box changes in the first 6.0 s of its fall.
(b)[2]
State and explain what happens to the gravitational potential energy of the box during the first 6.0 s.
(c(i))[2]
Use the graph in Fig. 1.2 to determine the speed of the object when it is moving with constant speed.
(c(ii))[1]
State the size of the resultant vertical force on the box when it is falling at constant speed.
(d)[3]
Use the graph in Fig. 1.2 to determine the distance covered by the box during the first 6.0 s.
(e)[1]
Without calculation, describe how Fig. 1.2 shows that the deceleration of the box is greater than the acceleration of the box.
