A hi-tech high-powered catapult is located at point A and isaimed at an angle of = 45 ° with the horizontal.
The projectile launched from the catapult is just able to clearthe peak of the mountain at the top of its
trajectory. The elevation of the catapult is 423 m above sealevel and the distance d is 4031 m.
Find the following:
(a) The velocity V0 that the projectile leaves thecatapult (in m/s),
(b) The time it takes the projectile to reach the peak of itstrajectory (in seconds),
(c) The maximum height above sea level, h, the projectilereaches (in metres),
(d) The time it takes for the projectile to hit the water (inseconds), and
(e) The range, R, of the projectile (in metres).
