Answer all the questions in the spaces provided.

(a)

Complete Table 1.1 by stating whether each of the quantities is a vector or a scalar.

Table 1.1

(b)

The variation with time $t$ of the velocity $v$ of an object is shown in Fig. 1.1.

Fig. 1.1

(i)

Determine the acceleration of the object from time $t = 0$ to time $t = 4.0\ \text{s}$ .

acceleration = ______ $\text{m s}^{-2}$

(ii)

Determine the distance moved by the object from time $t = 0$ to time $t = 4.0\ \text{s}$ .

distance = ______ $\text{m}$

(c)

(i)

Define force.

(ii)

The motion represented in Fig. 1.1 is caused by a resultant force $F$ acting on the object.

On Fig. 1.2, sketch the variation of $F$ with time $t$ from $t = 0$ to $t = 12.0\ \text{s}$ .
Numerical values of $F$ are not required.
