Assume you launch a projectile very close to the left edge of the building. It has a height of 500 meters. It follows a parabolic trajectory and just barely misses the right edge of the building and keeps falling to the ground. If the initial velocity is 26 m/s at an angle of 40° with respect to the top of the building what is:
a) the x and y components of the initial velocity?
b) the maximum height the projectile reaches?
c) the time it takes to reach this height?
d) the length of time the projectile is over the building?
e) the approximate length of the building?
f) the velocity and angle the projectile is just as it passes the edge of the building?
