Question

A car accelerates uniformly from 18 kilometre per hour to 36 km per hour in 5 seconds calculate acceleration and distance covered by the car in that time

Answer 1

the correct answer is

u =18km/hr=18×5/18

=5m/s

v=36km/hr =36×5/18

=10m/s

t=5sec

a= ?

a= v-u/t

a=10-5/5

=5/5

=1m/s2

d=?

v2-u2=2as

v2-u2/2a=s

100-25/2=s

37.5m)=s

Answer 2

Here is your answer

V = final velocity

U= initial velocity
