Question

A car travels at 54 km/hr speed up to 72 km/hr in 10 seconds find the acceleration of the car? ​

Answer 1

Answer:

0.5m/s^2

Explanation:

Initial velocity=u=54km/hr=15m/s

Final velocity =v=72km/hr=20m/s

Time taken. = t= 10seconds

v= u+at

20= 15+10a

10a= 5

a= 0.5m/s^2

HOPE IT WILL HELP YOU

Answer 2

Explanation:

54kmph=54x5/18 mps=15mps

72kmph=72x5/18 mps=20mps

Now, a=(v-u)/t

a=(20-15)/10=5/10=0.5 m per second square

So, the acceleration is 0.5(m/s^2).
