A bus starts moving with uniform acceleration from its position of rest. It moves 48 m in 4 s. On applying the brakes, it stops after covering 24 m. Find the deceleration of the bus.

Text Solution

Verified by Experts

(i) What is the initial velocity of the bus?
If the bus moves 48 m in 4 s, find the velocity of the bus at the end of 4 s.
Use the formula, `s=ut+(1)/(2) at^(2) and v=u+at`
When brakes are applied, the bus stops after covering 24 m.
What is the final velocity of the bus?
Then, find the deceleration of the bus by using the formula, `v^(2)-u^(2)=2as`.
(ii) `12ms^(-2)`
