A balloon starts rising from the ground with an acceleration of 1.25 m/`s^2`. A stone is released from the balloon after 10s. Determine
(i) maximum height of stone from the ground.
(ii) time taken by stone to reach the ground.
(Assume, g = 10 m/`s^2`)

A balloon starts rising from the ground with a constant acceleration of 1.25 m/ s^2 . After 8s, a stone is released from the balloon. Find the time taken by the stone to reach the ground. (Assume, g = 10m/ s^2 )

A ball is dropped from a building. It takes 4s to reach the ground. The height of the building is (use g = 10 m//s^(2) )

A stone is thrown vertically up from the tower of height 25m with a speed of 20 m/s What time does it take to reach the ground ? (g=10 m//s^(2))

A bus can accelerate with an acceleration 1m//s^2 . Find the minimum time for the bus to reach the speed of 100 km/s from 50 km/s.

An object is thrown upwards with an initial velocity of 17 m/sec from a building with 12 m height. It is at a height of S = 12 + 17t – 5t^(2) from the ground after a flight of ‘t’ seconds. Find the time taken by the object to touch the ground.

A ball is thrown up at a speed of 4.0 m/s. Find the maximum height reached by the ball. Take g=10 m//s^2 .

A ladder 10 m long reaches a window 8 m above the ground. Find the distance of the foot of the ladder from the base of the wall.

A ball is thrown vertically upward from the ground with an initial velocity of 39.2 m/sec. If the only force considered is that attributed to the accleration due to gravity , find (i) how long will it take for the ball to strike the ground ? (ii) the speed with which will it strike the ground ? and (iii) how high the ball will rise ?
