A bus decreases its speed from 80 km h-1 | Class 9 Science Chapter Motion, Motion NCERT Solutions

Question:

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

Answer:

Initial speed of the bus, u = 80 km/h =

                                           

Final speed of the bus, v = 60 km/h = 

                                         

Time take to decrease the speed, t = 5 s

Here, the acceleration of bus is -1.112 m/s2
