Question

A bus decrease its speed from 80km/hour to 60km/hour in 5sec . find its acceleration?

Answer 1

Hey mate!

Here's your answer!!

Initial velocity u = 80 km/h

$\frac{80 \times 1000}{60 \times 60} = 22.22m |s$
Final velocity u = 60km/h
$\frac{60 \times 1000}{60 \times 60} = 16.66m |s$

Time t = 5 sec, a = ?
$a = \frac{v - u}{t}$
$= \frac{16.66 - 22.22}{5} = 1.11m |s {}^{2}$
The acceleration of bus is -1.11 m/s²

Hope it helps you!!!
