answered-by-expert Expert Answer

O-A: The bus is accelerating. Its speed increases from 0 to 20 m/s in 10 seconds.

A-B: The bus is moving at a steady speed of 20 m/s for 10 seconds.

B-C: The bus is decelerating. Its speed decreases from 20 m/s to 0 in 6 seconds.

C-D: The bus is stationary. It has stopped.

D-E: The bus is accelerating. Its speed is gradually increasing from 0 to 10 m/s.

E-F: The bus is moving at a steady speed of 10 m/s.

Starting from rest, an object is uniformly accelerated to a speed of 60m/s in 20s. The object travels with this speed for next 40s and is then brought to rest by a uniform retardation in the next 30s.Sketch velocity time graph and calculate the acceleration, retardation and the total distance travelled. Hint: acceleration =rate of change of velocity.  distance covered =area under velocity-time graph .
