4. In 1978, Geoff Capes of the United Kingdom won a competition for throwing 5 lb bricks; he threw one brick a distance of 44.0 m. Suppose the brick left Capes' hand at a velocity of 20.8 m/s
at 45.0° with respect to the horizontal.
(a) What was the maximum height reached by the brick?
(b) If Capes threw the brick straight up with the same initial velocity, what would be the
maximum height the brick could achieve?
