Question 5

A stone is thrown with speed $\text{ ms}^{-1}$ from a point $O$ , 1.0 m above the horizontal ground, at an angle $\alpha^\circ\,$ to the horizontal. The stone reaches a maximum height of 6.0 m above the ground. The stone then strikes a target at point $A\,$ on the ground (0 m height) at a horizontal distance of 10 m from $O$ . The stone is modeled as a particle moving under gravity.

a.

Find the value of $U$ .

[6]

b.

Find the size of angle $α\alpha$ .

[3]

c.

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