Question

A car accelerates uniformly from 18 km/h to 36 km/h in 5 minutes. The acceleration is:​

Answer 1

Answer:

1/60 m/s2

Explanation:

5 minutes= 5*60 = 300 second

18 km/h = 18*1000/3600 m/s = 5m/s

36 km/h = 36*1000/3600 m/s = 10m/s

{1km = 1000 meter

1hour = 3600 seconds}

acceleration= increase of speed in a time interval

= (final speed - initial speed)/time

=(10-5)/300 m/s

= 1/60 m/s2
