QUESTIONS
Q11. Figure shows x-t graph of a particle. Find the time t such that the average velocity of the particle during the period 0 to t is zero.

Q12. A particle starts from a point A and travels along the solid curve shown in figure. Find approximately the position B of the particle such that the average velocity between the positions A and B has the same direction as the instantaneous velocity at B.

Q13. An object having a velocity 4.0 m/s is accelerated at the rate of 1.2ms2 for 5.0s. Find the distance traveled during the period of acceleration.

Q14. A person travelling at 43.2 km/h applies the brake giving a deceleration of 6.0mss2 to his scooter. How far will it travel before stopping?

Q15. A train starts from rest and moves with a constant acceleration of 2.0ms2ms2 for half a minute. The brakes are then applied and the train comes to rest in one minute. Find a. the total distance moved by the train, b. the maximum speed attained by the train

Q16. A bullet traveling with a velocity of 16 m/s penetrates a tree trunk and comes to rest in 0.4 m. Find the time taken during the retardation.

Q17. A bullet going with speed 350 m/s enters concrete wall and penetrates a distance of 5.0 cm before coming to rest. Find the deceleration.

Q18. A particle starting from rest moves with constant acceleration. If it takes 5.0 s to reach the speed 18.0 km/h find a. the average velocity during this period, and b. the distance traveled by the particle during this period.

Q19. A driver takes 0.20 s to apply the brakes after he sees a need for it. This is called the reaction time of the driver. If he is driving a car at a speed of 54 km/h and the brakes cause a deceleration of 6.0ms2, find the distance traveled by the car

Q20. A police is chasing a culprit going n a motorbike. The motorbike crosses a turning at a speed of 72 km/h.
The jeep follows it at a speed of 90 km/h, crossing the turning ten seconds later than the bike. Assuming that they tavel at constant speeds, how far from the turning will the jeep catch up with the bike?
