Question

the acceleration of a car is 12 metre per second square that speed up from 12 metre per second is 15sec find final velocity​

Answer 1

Answer:

-33m/s²

Explanation:

Given:-

1. Acceleration given= 3m/s²
2. Initial velocity = 12m/s²
3. Time given= 15 seconds

Formula for acceleration is:-

u-v/t

Putting the values in the formula:-

a=u-v/t

3= 12-v

-------

15

45=12-v

45-12=-v

33=-v

The final velocity of the car is -33m/s, that means that the car is regarding or in the retardation.

Hope my answer is correct and you liked the solution !
