Question

Can some one show step by step of how to solve by using the quadratic kinematic and using (Vix) times the Sin of theta (when theta=the angle of 420

Mt. Asama, Japan, is an active volcano. In 2009, an eruption threw solid volcanic rocks that landed 1 km horizontally from the crater. If the volcanic rocks were launched at an
angle of 42° with respect to the horizontal and landed 935 m below the crater, find the following.
(a) their initial velocity (Enter the magnitude in m/s.)
m/s
(b) their time of flight (in s)
S
