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 travelled by the particle during this period.

A bullet travelling 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.

A bullet going with speed 350 m/s enters a concrete wall and penetrates a distance of 50 cm before coming to rest. Find the deceleration.

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 6.0 m/s², find the distance travelled by the car after he sees the need to put the brakes on.
