Question

a car is moving with Finite velocity and is stopped in 25 seconds by applying brakes .retardation due to brakes is 3.2 metre per second square find the initial velocity of the body. (find the answer in CGS and Si system)​

Answer 1

Explanation:

1. v = u +at
2. 0=u +3.2.25
3. u=80 m/s
4. to convet it into CGS
5. WE WILL MULTIPLY IT BY 5/18
6. =200/9 cm/s
7. 22.2 cm /s
