A stone is thrown from a bridge at an angle of 30º down with the horizontal with a velocity of 25 m/s. If the stone strikes the water after 2.5 sec then calculate the height of the bridge from the water surface-

(b) A stone is thrown from a bridge at an angle of 30^(@) down with the horizontal with a velocity of 25 m//s . If the stone strikes the water after 2.5 seconds then calculate the height of the bridge from the water surface (g=9.8 m//s^(2)) .

A ball dropped from a bridge strikes the water in 5 s. Calculate the height of the bridge

A stone is thrown from the top of a tower at an angle of 30^(@) above the horizontal level with a velocity of 40 m/s. it strikes the ground after 5 second from the time of projection then the height of the tower is

A stone is thrown from the top of a tower at an angle of 30^(@) above the horizontal level with a velocity of 40 m/s. it strikes the ground after 5 second from the time of projection then the height of the tower is

A stone is thrown from the top of a lower at an angle of 30^(@) up with the horizontal with a velocity of 16 m//s . After 4 sec. of flight it strikes the ground. Let the heighty of lower is H .meter. Then the value of (H)/(12) is: (g = 10 m//s)

A stone is dropped freely in a river from a bridge. It takes 5 s to touch the water surface in the river. Calculate : the height of the bridge from the water level .

To estimate the height of a bridge over a river, a stone is dropped freely on the river from the bridge. The stone takes 2 s to touch the water surface in the river. Calculate the height of the bridge from the water level. Take g=9.8m//s^(2)

A ball is thrown vertically upwards with a velocity 4.9 m/s from the floor of a bridge over water. The ball strikes water after 2 seconds. Calculate the height of the bridge.

A pebble is thrown vertically upwards from a bridge with an initial velocity of 4.9 m/s. It strikes the water after 2s. If acc. Due to gravity of 9.8 m//s^(2) (a) what is the height of the bridge ? (b) with what velocity does the pebble strike the water ?

A stone is thrown up with a velocity of 20 m/s. Neglecting air resistance calculate the height that the stone will reach
