A stone is throun with an initial speed of ` 4.9 ms^(-1)~ from a bridge in vertical upward direction. If falls down in water after `2` seconds. The height of the bridge is.

A stone is thrown with an initial speed of 4.9 m/s from a bridge in vertically upward direction . It falls down in water after 2 sec. Find height of the bridge.

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 ball is thrown vertically upwards from the top of a tower at 4.9 ms^(-1) . It strikes the pond near the base of the tower after 3 seconds . The height of the tower is

Two stones are thrown from the same point with velocity of 5 ms^(-1) one vertically upwards and the other vertically downwards. When the first stone is at the highest point the relative velocity of the second stone with respect to the first stone is,

A body is thrown vertically upwards with an initial velocity of 9.8 "ms"^(-1) . What is its speed and direction after 1 s (g=9.8 "m/s"^2 ). Also, find the height to which it will rise.

(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 stone is thrown vertically up from a bridge with velocity 3m/s. If it strikes with water under the bridge after 2sec, the bridge is at a height of (g=10m/s)

The velocity-time graph of a stone thrown vertically upward with an initial velocity of 30ms^(-1) is shown in the figure. The velocity in the upward direction is taken as positive and that in the downward direction as negative. What is the maximum height to which the stone rises?
