A projectile is launched from the origin with speed v0 at angle θ0 above the horizontal.
(i) Obtain the time taken to reach the point of maximum height.
(ii) Hence derive an expression for the maximum height H reached by the projectile.
(iii) Show that, when the projectile returns to the initial vertical level, the time taken to descend from the highest point equals the time of ascent.
a. (i) Time to reach maximum height
b. (ii) Expression for maximum height
c. (iii) Equality of ascent and descent times
