Question 27

Diagram showing balls P and Q projected upwards from A and B on horizontal ground 56 m apart, with their initial speeds and angles labelled.

The points A and B lie 56 m apart on horizontal ground. At time t=0t = 0t=0 two balls, P P\,P and QQQ, are projected from the points A and B. Ball P P\,P is projected with speed 28 ms-1 at an angle of 30∘ 30^\circ\,30∘ to the horizontal. Ball Q Q\,Q is projected with speed U ms−1U \text{ ms}^{-1}U ms−1 at an angle of θ \theta\,θ to the horizontal. At time t=2t = 2t=2, P P\,P and Q Q\,Q collide.

a.

Find the velocity of P P\,P the instant before it collides with QQQ.

[6]
b.

Find (i) the size of angle θ \theta\,θ and (ii) the value of UUU.

[6]
c.

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