A projectile is kicked horizontally off a tall building with an initial velocity of 13.7 m/s. The projectile lands 56.2 m away from the base of the building. How long is the projectile in the air? How tall is the building? What is the velocity of the projectile when it strikes the ground?

Answer 1

u = 13.7
t = 56.2/13.7 seconds in air

h = .5 g t^2 for height

v = g * t vertical + 13.7 horizontal
