A stone is thrown from a point at a distance `a` from a wall of height b . If it just clears the wall , the maximum height reached by the stone , if the angle of projection is `alpha`, is

Maximum height attained from the point of projection is:

A body is thrown from the surface of the earth with velocity (gR_(e))//12 , where R_(e) is the radius of the earth at some angle from the vertical. If the maximum height reached by the body is R_(e)//4 , then the angle of projection with the vertical is

A body is thrown vertically up reaches a maximum height of 78.4 m. After what time it will reach the ground from the maximum height reached ?

A stone is thrown vertically upwards. When stone is at a height half of its maximum height, its speed is 10 ms^-1 , then the maximum height attained by the stone is ( g= 10 ms^(-2) )

A stone is thrown vertically upwards. When stone is at a height half of its maximum height, its speed is 10 ms^-1 , then the maximum height attained by the stone is ( g= 10 ms^(-2) )

Two stones are projected so as to reach the same distance from the point of projection on a horizontal surface. The maximum height reached by one exceeds thr other by an amount equal to half the sum of the height attained by them. Then angle of projection of the stone which attains smaller height is

A heavy stone is thrown from a cliff of height h with a speed v. The stone will hit the ground with maximum speed if it is thrown

If a stone is to hit at a point which is at a distance d away and at a height h (Fig. 5.200) above the point from where the stone starts, then what is the value of initial speed u if the stone is launched at an angle theta ? .

A ball thrown by one player reaches the other in 2 s . The maximum height attained by the ball above the point of projection will be about.
