The apple is thrown vertically upwards with speed 3.0 m s−1.
The knife is thrown with speed 8.0 m s−1.
When the knife and apple collide, they are both at the highest points of their trajectories.
At what angle from the horizontal, θ, was the knife thrown?
(You may ignore air resistance. Take the acceleration due to gravity to be 10 m s−2.)
