Question 44

In this question use $\text{ m s}^{-2}$ .

A particle is projected from a point $O$ with an initial speed $u$ at an angle of $40∘40^\circ$ above the horizontal.

The particle lands at a point $P$ which is 15 metres vertically below the level of $O$ .

The particle takes 1.2 seconds to reach the maximum height of its trajectory.

Find the value of $u$ .

[3]

Find the total time that the particle is in flight.
