A boy standing at the top of a water of `20 m` height drops a stone. Assuming, `g = 10 ms^(-2)`, the velocity with which it hits the ground is

A boy standing at the top of a tower of 20m of height drops a stone. Assuming g=10ms^(-2) , the velocity with which it hits the ground is :-

A boy standing at the top of a tower of 20 m . Height drops a stone. Assuming g = 10 ms^-2 towards north. The average acceleration of the body is.

A stone is thrown horizontally with velocity g ms^(-1) from the top of a tower of height g metre. The velocity with which it hits the ground is (in ms^(-1) )

A body is dropped freely under gravity from the top of a tower of height 78.4 m. Calculate : the velocity with which it strikes the ground. Take g = 9.8 m s^(-2) .

A ball is dropped from a height of 20 m and rebounds with a velocity which is 3/4 of the velocity with which it hits the ground. What is the time interval between the first and second bunces (g=10m//s^(2))

A stone is thrown horizontally with the velocity u = 15m/s from a tower of height H = 25 m. Find (i) the time during which the stone is in motion , (ii) the distance from the tower base to the point where the stone will touch the ground (iii) the velocity v with which it will touch the ground (iv) the angle theta the trajectory of the stone makes with the horizontal at the point stone touches the ground (Air resistance is to be neglected). (g=10ms^(-2)) .

A ball is thrown vertically upwards from the top of a building of height 24.5 m with an initial velocity 19.6 m s^(-1) . Taking g = 9.8 ms, calculate : the velocity with which it will strike the ground .

From the top of a tower, 80m high from the ground a stone is thrown in the horizontal direction with a velocity of 8 ms^(1) . The stone reaches the ground after a time t and falls at a distance of d from the foot of the tower. Assuming g=10ms^(2) , the time t and distance d are given respectively by

A stone is thrown vertically up at 20 m/s from a tower 80 m height. The speed with which it hits the ground is [g=10 "m/s"^2]

A stone is dropped freely from the top of a tower and it reaches the ground in 4 s. Taking g = 10 m s^(-2) , calculate the height of the tower.
