Question

Calculate the time taken to change the velocity of the car from 10m/s to 25m/s if the acceleration is 5m/s^2​

Answer 1

Answer:

3s

Explanation:

v = u +at

25 = 10 + 5t

25 - 10 = 5t

15 = 5t

t=  15/5

t= 3 secs

Answer 2

Answer:

3 seconds

Explanation:

acceleration = v-u/t

5= 25-10/t

then cross multiply to get:

5t= 15

5t/5= 15/5

t = 3
