Question 62

A ball travels from O along a parabolic path to A, with a horizontal ground line below, a vertical 2 m arrow at O, and an initial angle labelled α°.

A ball is projected with speed 14 ms-1 from the point OOO, 2 m above the ground. The ball is projected from O O\,O at an angle of α∘\alpha^\circα∘, where 0<α<450<\alpha<450<α<45. In the motion the ball passes through the point A A\,A 0.75 m above the ground and a horizontal distance of 15 m from OOO.

a.

Find the maximum height reached by the ball above the horizontal ground.

[6]
b.

Find the size of angle α\alphaα.

[3]
c.

State one limitation of the model that could affect the accuracy of your answers.
