Question

A car is starting from rest and moving with uniform
acceleration attains a speed of 90 km/h in 20 second
on a express highway Calculate its uniform
acceleration ​

Answer 1

Explanation:

u=0 m/s

v=90 km/hr

=90×5/18 m/s

=25 m/s

t=20s

Acceleration= v-u/t

=25-0/20

=25/30

=5/4

=1.25m/s²
