Consider a rock that is thrown off a bridge of height 27 m at an angle θ = 24° with respect to the horizontal as shown in the figure above. If the initial speed the rock is thrown is 12 m/s, find the following quantities:
(a) The time it takes the rock to reach its maximum height.
(b) The maximum height reached by the rock.
(c) The time at which the rock lands.
(d) The place where the rock lands.
(e) The velocity of the rock (magnitude and direction) just before it lands.
