Question

A scooter acquires 54km/hr in 15 sec just after the start. Calculate the acceleration of the scooter

Answer 1

Explanation:

acceleration = change in velocity/time

final velocity =54 km/hr = 15 m/s

initial velocity =0

time =15 sec

acceleration = (15-0)/15 = 1 m/sec^2

Answer 2

velocity=54km/hr=54000/3600m/s=15m/s

the acceleration is

=(15/15)m/s²=1m/s²
