Question

12. The speed of car changes from 30 m/s to 20 m/s in 5 seconds. Calculate the acceleration
produced and distance travelled by the car in these 5 seconds.
​

Answer 1

Explanation:

acceleration= change in velocity/ time

v(i)= 30m/s

v(f)= 20m/s

change in velocity= 10m/s

time= 5s

10m/s/5s

=2m/s2
