Q.III) Answer the following
1. Following is the data of a car travelling at regular instants of time
(b). Determine the distance moved by the car.
ANSWER ONLY Q.1(b) please

Answer 1

Formula for acceleration is,

$\frac{v - u}{t}$

Where v - final velocity

u - initial velocity

and t - time taken

Substituting these values, we get,

$a = \frac{15 - 0}{30} \\ a = \frac{1}{2} \\ a = 0.5 \: m {s}^{ - 2}$

Using the second equation of motion,

$s = ut + \frac{1}{2} a{t}^{2}$

We get,

$s = (0)(30) + \frac{1}{2} (0.5)( {30}^{2} ) \\ s = \frac{1}{2} 450 \\ s = 225m$
