Question

a car decreases its speed from 80m/s to 60m/s in 10s.find the acceleration of car​

Answer 1

ANSWER

Such a case is called deceleration

Deceleration is reduction in speed or rate while acceleration is increase in speed or rate.

In this case, your car is slowing down, so this case is a case of deceleration.

Step by step explanation

To find it, we can use the same formula of acceleration

Formula of acceleration=

A/D= final velocity- Initial velocity   or [v2-v1]/ t

               elapsed time

D= [80m/s- 60m/s] ÷ 10s

D= 20m/s÷ 10s

∴ D = 2 m/s²

Answer: 2 m/s²

Hope the explanation helped.
