Answer 2

Step by step explanation:

To find:

a car starts from rest and attains a velocity of 54 km/h in 5s

calculate the acceleration?

Given:

a car starts from rest and attains a velocity of 54 km/h in 5s

Note:

54km/h

=5/18*54m/s

=5*3m/s

=15m/s

so,54km/h=15m/s

Solution:

(15/5)m/s^2

=3m/s^2

Answer:

3m/s^2

Used formula:

Accelaration=velocity/time
