Question

Abus decreases its speed from
80 km h-1 to 60 km h-1
in 5 s.
Find the acceleration of the bus.​

Answer 1

Answer:

the acceleration of the bus is 4 km/h

Answer 2

Answer:

acceleration =∆v/∆t

= 20km in to m/sec(conversion) / time in second s

so we have given that

20km decrease in 5 sec

20×5\18=100/18 m/s(conversion done)

Explanation:

this implies for finding acceleration

acceleration = (100/18)/5

=20/18 m/s ..

in exaxt figures acceleration equals to

1.11111m/s
