Question

speed of a car decreases from 8 m/s to 60m/s in 5s calculate acceleration of the car​

Answer 1

Answer:

4 m/s^2

Explanation:

I think it should be from 80 m/s to 60 m/s.

Then, change in velocity = (80 - 60) m/s = 20 m/s

Rate of change of velocity

= Change in velocity / Time taken

= ( 20 m/s) / (5 s)

= 4 m/s^2

Answer 2

Explanation:

initial 8 m per second

final 60 m per second

t= 5 s

a= v- u/t

60 - 8/5

52/5

10.40 m = a
