Question

A bus decreases its speed 12 kilometre per hour in 5 seconds. find the acceleration of the bus?

Answer 1

$12 \: kmph= (\frac{12 \times 10}{36} )mps = 3.3 \: metre \: per \: second$

Therefore, Total decreased speed =
$\frac{33 \times 5}{10} = 16.5 \: m$

Now, Acceleration = $\frac{33}{5×10}=0.66 mps^2$
