A stone is dropped from a height of 20 m .
(i) How long will it take to reach the ground?
(ii ) What will be its speed when it hits the ground? `(g= 10 m//s^2)`

A particle is dropped from a tower 180 m high. How long does it take to reach the ground ? What is the velocity when it touches the ground ? Take g=10m//s^(2) .

ball is thrown vertically upwards with a velocity of 20 m/s from the top of a building of height 40 m from the ground. (i) How high the ball reaches? (ii) How long will it take to reach the ground ? (iii) What is the speed at which it strikes the ground?

A balloon is ascending at the rate of 9.8 m//s and is 39.2 m above the ground when a package is dropped. (a) How long does the package take to reach the ground? (b) with what speed does it hit the ground ? (g = 9.8 m//s^(2))

A hot-air balloon is ascending at the rate of 12 m/s and is 80 m above the ground when a package is dropped over the side. (a) How long does the package take to reach the ground ? (b) With what speed does it hit the ground ?

A body dropped from a height of 5m. Reaches the ground in 1 s. if it takes 2 s to reach the ground , find the height from which it is dropped.

A packet is dropped from a helicopter, which is ascending at a rate of 16m/s , when it is at a height of 14.4m above the ground. (i) How much time it will take the packet to reach the ground? (ii) With what velocity it will hit the ground?

A man drops a 10 kg rock from the top of a 5 m ladder. What is its speed just before it hits the ground ? What is its kinetic energy when it reaches the ground ? ( g = 10 m//s^(2) )

A stone is dropped from the top of tower. When it has fallen by 5 m from the top, another stone is dropped from a point 25m below the top. If both stones reach the ground at the moment, then height of the tower from grounds is : (take g=10 m//s^(2) )
