another quest. a small steel ball is dropped from a height of 2.5m into glycerin jar. it hits the surface of glycerin with certain velocity and sinks into the bottom by losing its 20% of its velocity at the surface. if the time taken to reach the bottom after it si dropped is 2 sec. and velocity in glycerin is lost at constant rate, then fiind the average velocity of the ball of journey

- Brake applied to a car produce a uniform retardation of 90m/s .if the car was travelling with a velocity of 27m/s.than what distance will it cover before coming to rest?
- A car is travelling with a speed of 36km/h. The driver applies the brakes and retards the car uniformly. The car is stopped in 5 seconds. Find i) Retardation of the car ii) Distance travelled before it is stopped.
- A stone is thrown vertically upward after how much time it will be at height of 5m
- A particle which is moving in a straight line with constant acceleration describes distances of 10 m and 15 m in two successive seconds. find the acceleration
- a car has uniform acceleration of 8m/s². what distance will it cover in 20 s after starting from rest.?
- a=-0.5 Speed = 90km/h find distance
- An object starting from rest travels 20m in the first 2s and 160m in the next 4s. What will be the velocity after 7s from the start?
- The water drop falls at regular intervals from a tap 9 m above the ground. The fourth drop is leaving the tap at the instant, the first drop touches the ground. How high is the third drop at that instant?
- a stone is allowed to fall from the top of a tower of height 200m and at the same time an another stone is projected vertically upwards from the ground with a velocity of 50 metre per second calculate where and when the two stones will meet. ( take g = 10 metre per second square)
- a train starting from Rest attains a velocity of 72 km /h in 5 minutes. Assuming that the acceleration is uniform,find the acceleration and the distance travelled by the train for attaining this velocity.
