The first question
![12–89. The girl at A can throw a ball at va = 10 m/s.
Calculate the maximum possible range R = Rmax and the
associated angle 0 at which it should be thrown. Assume the
ball is caught at B at the same elevation from which it is
%3D
thrown.
12–90. Show that the girl at A can throw the ball to the
boy at B by launching it at equal angles measured up or
down from a 45° inclination. If va = 10 m/s, determine
the range R if this value is 15°, i.e., 0, = 45° – 15° = 30°
and 62 = 45° + 15° = 60°. Assume the ball is caught at the
same elevation from which it is thrown.
