Question

A power motorcycle can accelerate from rest to 28 m/s in only 4sec .how far does it travel in a that time

Answer 1

$s = ut +( 1 \div 2)a {t}^{2}$
where,
s is the distance travelled.
u is the initial velocity, which in this case is 0.
t is time in seconds.
a is the acceleration given.

So,
$s = 0(4) + (1 \div 2) \times 28 \times {4}^{2}$
$s = 224m$
