Question

A car uniformly changes its speed from 2 m/s to 54 km/h in 10 s. Find its acceleration.​

Answer 1

Explanation:

here initial velocity = 2m/s

final velocity =54km/h

=(54×5/18)m/s

=15 m/s

acceleration =final velocity -intial velocity /time

=15-2/10

=13/10

acceleration . =.1.3m/s²

Answer 2

Given,

Initial velocity, u = 2 m/s

Final velocity, v = 54 km/h = 54 (5/18) m/s = 15 m/s

Time, t = 10 seconds

Accelaration:

a = (v – u)/t

a = (15-2)/10

= 13/10

=1.3m/s
