Question

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

Answer 1

to find the acceleration =v-u/t

final velocity = 50×5/18=13.88.m/s

initial velocity=20×5/18=5.55m/s

so v-u=13.88-5.55=8.33m/s

so 8.33/time=8.33/10=0.833m/s^2

hope it may help you
