Question

a car increases its speed from 20 kilometre per hour to 50 kilometre per hour in 10 second what is its acceleration

​

Answer 1

Answer:

Explanation:a = (v2-v1)/(t2-t1)

v2-v1 = 30 kmph

= 30×5/18 m/s

= 25/3 m/s

t2-t1 = 10s

a= 25/(3×10) = 5/6 m/s^2

Answer 2

a car increases its speed from 20 kilometre per hour to 50 kilometre per hour in 10 second than its acceleration is

=0.71 m/s
