(a)[2]
Complete Table 1.1 by placing a tick (✓) in the correct column to show whether each listed quantity is a scalar or a vector.
(b)
A toy train travels along a straight length of track. Fig. 1.1 shows how the distance $d$ moved by the train varies with time $t$.
(b(i))[1]
Describe qualitatively the train’s motion from time $t = 0$ to time $t = 1.0\,\text{s}$.
(b(ii))[2]
Determine the speed of the train at time $t = 2.0\,\text{s}$.
(c)[1]
The straight section of track in part (b) belongs to the loop of track shown in Fig. 1.2. The train makes exactly one full lap of the loop. State and explain the average velocity of the train for the one complete lap.
