Question

A bus starting from rest moves with a uniform acceleration. if it travels 100 m in 5s what is the value of acceleration

Answer 1

Here,
$u = 0 \frac{m}{s} \\ s = 100m \\ t = 5s$
On applying 2nd eq. of motion, we get,
$s = ut + \frac{1}{2} a {t}^{2}$
$100 = 0 \times 5 + \frac{1}{2} a {5}^{2}$
Or,
$100 = \frac{25a}{2}$
On solving,
$a = 200 \div 25 = 8 \frac{m}{ {s}^{2} }$
