Question

10% -2im.
Example 2
A car is moving with the initial velocity
15 ms. Car stoped after 5s by application
of breaks. Find the retardation
(Decelaration)

​

Answer 1

Answer:

Therefore, Retardation= -3m/s²

Explanation:

Given, u = 15 m/s, v = 0m/s and t = 5s

Now, By using Newton's 1st Equation of Motion i.e.

=> v = u + at

=> 0 = 15 + a(5)

=> -15 = a*5

=> -15/5 = a

=> a = -3m/s²

Hope it helps you.

Thanks.
