Question

A car accelerates uniformly from 18km/h in 5sec. Calculate the accelaration and the distance covered by the car in that time.

Answer 1

Answer:

Explanation:

time=5sec

u=0

v=18km/h=5m/s

a=v-u by t

=5-0 by 5

=5 by 5

=1 m/s

Equation of motion,s=ut+(1/2)at2

u=18 km/h=5 m/s

t=5 s

a=1 m/s2

s= (5*5)+(1/2*1*5*5)

s=25+12.5 i.e., s=37.5 m
