9. An aircraft leaves airport P and flies on a
bearing 060°. From a distance of 10 km
due cast of P. another aircraft leaves
airport R and flies on a bearing of 330°
Both planes meet at Q. Using ruler and a
pair of compasses only, with a scale of
1 cm to 1 km
a) construct triangle PQR.
b) how far is from:
i) P.
ii) R2
c) measure ZPOR
d) Calculate how far north of R, Qis,
correct to one decimal place.

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
