(a)[2]
The student takes two measurements to find the average speed of the trolley as it moves down the slope. State the two measurements. For each one, suggest the instrument used to make the measurement.
(b(i))[2]
Determine the speed of the trolley at time = 2.0 s.
(b(ii))[3]
Determine the distance travelled by the trolley from time = 0 to time = 4.0 s.
(b(iii))[2]
Using the information in Fig. 1.1, describe the motion of the trolley from time = 0 to time = 10 s.
