Question

A bus decreases its speed from
80 km per h to 60 km per h in 5 s.
Find the acceleration of the bus.​

Answer 1

Answer:

Here's your answer

u= 80 km hr

u= 22.22 m sec

v= 60km hr = 16.66 m sec

t is 5 s

$a = \frac{v - u}{t}$

$a = \frac{16.66 - 22.22}{5} = \frac{ - 5.56}{5 } = - 1.112</strong><strong> </strong><strong> </strong><strong>metre</strong><strong> </strong><strong> </strong><strong>per</strong><strong> </strong><strong>second</strong><strong> </strong><strong>square</strong><strong> </strong><strong>$

hope it helps
