(a)[2]
Complete Table 1.1 by indicating for each quantity whether it is a vector or a scalar. The quantities are acceleration, power and work.
(b)
Fig. 1.1 shows how the velocity $v$ of an object varies with time $t$.
(b(i))[2]
Determine the acceleration of the object for the interval from time $t = 0$ to time $t = 4.0\,\text{s}$.
(b(ii))[2]
Determine the distance moved by the object over the interval from time $t = 0$ to time $t = 4.0\ \text{s}$.
(c(i))[1]
Define force
(c(ii))[3]
The motion shown in Fig. 1.1 is produced by a resultant force $F$ acting on the object. On Fig. 1.2, sketch how $F$ varies with time $t$ from $t = 0$ to $t = 12.0\ \text{s}$. You do not need to include numerical values of $F$.
