Question

a car travelling with a uniform velocity is stops when brake is applied with the radiation of 1 metre per second square in 5 seconds calculate its initial velocity​

Answer 1

Answer:

u=5m/s

Explanation:

as

v=0,

u=?,

a=-1m/s square

t=5s

as we know

a=v-u/t

-1=0-u/5

-5=-u

therefore: u=5m/s
