Question

a car moving with a uniform velocity when its break was applied it is top in 5 second with retardation 1 minute per second square calculate its initial velocity?​

Answer 1

Answer:

5m/s

Explanation:

Given,

t=5s, a= -1m/s^2 and v=0m/s

Using first equation of motion,

v=u+at

0=u+(-1)*5

-u=-5

u=5
