Distinguish between uniform and non uniform acceleration. 5. A bus decreases its speed from 80 km/h in 5 sec. Finf the acceleration of the bus. 6. Starting from a stationary position, Rahul paddles his bicycle to attain a velocity of 6m/s in 30 s. Then he applies brakes such that the velocity of the bicycle comes down to 4m/s in the next 5s. Calculate the acceleration of the bicycle in both the cases.
7. What is the nature of the distance time graphs for uniform and non uniform motion of an object? 8. Derive the three equation of motion. 9. a stone is thrown vertically upward direction with a velocity of 5m/s. if the acceleration of the stone during its motion is 10m/sxs in the downward direction, what will be the height attained by the stone and how much the time will it take to reach there? 10. Draw the graph of distance time graph of an object moving with uniform and non uniform motion. 11. Draw the graph of velocity time graph of an object moving with uniform and non uniform motion. 12. An artificial satallite is moving in a circular orbit of radius 42250 km. Calculate its speed if it takes 24 hours to revolve around the earth. 13. A train sarting from a railway sation and moving with uniform acceleration attains a speed 40 km/h in 10 min. Find its acceleration. 14. What does the odometer of an automobile measure? 15.
