Question

a car moving at 20ms-1 changes its velocity to 36 ms- in 8 second what is the acceleration of the car​

Answer 1

Answer:

The cars change in velocity is 40m/s−20m/s=2 0m/

Answer 2

Answer:

Given-

Initial speed of car (u) =20m/s

Final speed of car (v) = 36m/s

To find-

Acceleration (a) =?

Solution-

Since we know that

Acceleration=Change in velocity w. r. to time

so

a=(v-u) /t

a=(36-20)/8

a=16/8

a=2 ms-2.
