Question

11. Projectile Calculations - Working Backwards and Different Height Calculations
1. A piggie is located 30.0 m away from the launch pad. If the launcher is fired at an 37°
angle and the angry bird takes 1.88 seconds to land on the pig. What was the launch
velocity with angle? (19.98 ms 37° above horizontal)
2. A bird is launched upwards at an angle 0 and reaches a maximum height of 45 mm in a
time of 0.543 seconds. The bird eventually hits its target 28 m away from the launch.
Determine the overall launch velocity of the bird. (26.3 ms 1 12° above horizontal)
3. A bird is launched from a catapult and on its way upwards it contacts a piggie that is
placed on a ledge that is 6.8 m above the catapult and 35 m away from the catapult. It
takes the bird 2.5 seconds to hit the piggie one the catapult. Determine the launch angle
and velocity needed to hit the piggie. (20.51 ms: 47° above horizontal)​
