Question #97de6

Acceleration = $1.5 \frac{m}{s^{2}}$ $1.5 m/s^2$
Distance covered = $75 m$ $75m$

Explanation:

Given $u = 0 \frac{m}{s}$ $u=0 m/s$ , $v = 15 \frac{m}{s}$ $v=15 m/s$ and $t = 10 s$ $t=10s$ , find $a$ $a$ and $s$ $s$ .

To find $a$ $a$ , we use $a = \frac{v - u}{t}$ $a= (v-u)/t$ .
$a = \frac{15 - 0}{10} = 1.5 \frac{m}{s^{2}}$ $a= (15-0)/10= 1.5 m/s^2$

To find $s$ $s$ , we use $s = \frac{u + v}{2} \cdot t$ $s=(u+v)/2 *t$ .
$s = \frac{0 + 15}{2} \cdot 10 = 75 m$ $s= (0+15)/2 *10 = 75m$
