A boy playing on the roof of a 10 m high building throws a ball with a speed of 10 m//s^(-1) at an angle of 30^(@) with the horizontal. How far from the throwing point will the ball be at a height of 10 m from the ground?

A boy playing on the roof of a 10 m high building throws a ball with a speed of 10 m/s at an angle 30 ^@ with the horizontal. How far from the throwing point will the ball be at the height of 10 m from the ground? (g = 10 m//s ^ 2 )

A boy playing on the roof of a 10 m high building throws a ball with a speed of 10 m/s at an angle 30 ^@ with the horizontal. How far from the throwing point will the ball be at the height of 10 m from the ground? (g = 10 m//s ^ 2 )

A boy playing on the roof of a 10 m high building throws a ball with a speed of 10 m//s at an angle of 30^(@) with the horizontal. How far from the throwing point will the ball be at the height of 10 m from the ground ? [ g = 10m//s^(2) , sin 30^(@) = (1)/(2) , cos 30^(@) = (sqrt(3))/(2)]

A boy playing on the roof of a 10 m high building throws a ball with a speed of 10 ms^-1 at an angle of 30^0 with the horizontal. How far from the throwing point will the ball be at the height of 10 m from the ground?given that g=10 ms^-2 , sin30^0=1/2 , cos30^0=sqrt3/2
