Question

Gogi applied brakes which caused retardation of 5m/s^2. Find the time taken to stop the scooty if his initial velocity is 40m/s. Pls explain with full detail

Answer 1

Answer:

8 sec .

Explanation:

Given :

Initial velocity ( u ) = 40 m / sec

When break applied final velocity becomes zero i.e. v = 0 m / sec

Retardation ( - a ) = 5 m / sec²

We have to find time :

From first equation of motion we have :

v = u +  a t

Putting values here we get :

0 = 40 - 5 t

- 5 t = - 40

t = 8 sec .

Hence time taken is 8 sec to stop the scooty .
