Question

3. A car increases its speed from 20 km/h to 50 km/h in 10 seconds . What is the acceleration. ?

Answer 1

Answer: 10800 km/hr^2

Explanation:

Acc= (final velocity - initial velocity)/ Time taken

{50 - 20}/(10/60×60)= 10800

Answer 2

Answer:

Explanation:

acceleration=v-u/t where v= final velocity ,u is initial velocity

a=50-20/10

=  30/10

= 3m/s sq

so acceleration of car = 3m/s  sq
