Question

A car is traveling at 30m/s it accelerates steadily for 5 s after which it is travelling at 50 m/s calculate its acceleration?

Answer 1

Formula for acceleration: a = v-v0/t
a is acceleration, v is final velocity and v0 is starting velocity, t is time
Now plug it in
a = 50m/s - 30 m/s = 20 m/s/ 5s = 4 m/s^2
The acceleration is 4 m/s^3

Answer 2

For this question , we should apply
a = v - u by t
Given - u = 30m/s
v = 50m/s
t = 5 secs
Solution :
a = v - u by t
a = 50 - 30 by 5
a = 20 by 5
( cut 5 and 20 because 5 x 4 = 20 )
a = 4 m/s^2

.:. The acceleration is 4 m/s^2
