Question

Find the initial velocity of a car which is stopped in 10 seconds by applying brakes . The retardation due to brakes is 2.5 m/s2​

Answer 1

Answer:

Explanation:

initial velocity=?

final velocity=0

time=10

accelaration=-2.5m/s2

a=v-u/t

-2.5=0-u/10

-2.5=-u/10

-2.5*10=-u

-25=-u

25=u

Answer 2

Answer:

25 is the answer and explanation in the above question
