A boy throws a stone at 40m/s,`60^(@)` above horizontal.The stone hits a fruit on a tree while decending at `45^(@)` below horizontal.Find the height of the fruit.

A stone is thrown at 25m//s " at " 53^(@) above the horizontal. At what time its velocity is at 45^(@) below the horizontal?

A ball is projected at an angle of 30^(@) above with the horizontal from the top of a tower and strikes the ground in 5s at an angle of 45^(@) with the horizontal. Find the height of the tower and the speed with which it was projected.

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 particle is projected from ground with velocity 40 m//s at 60^@ from horizontal. (a) Find the speed when velocity of the particle makes an angle of 37^@ from horizontal. (b) Find the time for the above situation. (C ) Find the vertical height and horizontal distance of the particle from the starting point in the above position. Take g= 10m//s^2 .

A balloon moves up vertically such that if a stone is thrown from it with a horizontal velocity v_(0) relative to it the stone always hits the ground at a fixed point 2v_(0)^(2)//g horizontally away from it. Find the height of the balloon as a function of time.

One second after the projection, a stone moves at an angle of 45^@ with the horizontal. Two seconds from the start, it is travelling horizontally. Find the angle of projection with the horizontal. (g=10 ms^(-2)) .

(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 boy throws a stone with a speed of V_(0) = 10 m/sec at an angle of theta_(0)= 30^(@) to the horizontal Find the position of the stone wrt the point of projection just after a time t = 1/2 sec.

A projectile is thrown with a velocity of 20 m//s, at an angle of 60^(@) with the horizontal. After how much time the velocity vector will make an angle of 45^(@) with the horizontal (in upward direction) is (take g= 10m//s^(2))-

A boy whirls a stone of small mass in a horizontal circle of radius 1.5m and at height 2.9m above level ground. The string breacks and the stone flies off horizontally and strikes the ground after travelling a horizontal distance of 10m . What is the magnitude of the centripetal acceleration of the stone while in circular motion ?
