Question

A ball is shot from the top of a building with an initial velocity of 16 m/s at an angle θ = 45 ∘ above the horizontal.

a. What are the x and y components of the initial velocity?

b. If a nearby building is the same height and 55 m away, how far below the top of the building will the ball strike the nearby building?

i. How long is the ball in the air, before it hits the
ground?
ii. How far from the launcher does the ball land on the
ground?

A ball is tossed from an upper-story window of a building. The
ball is given an initial velocity of 8.20 m/s at an angle of 15.0°
below the horizontal. It strikes the ground 4.00 s later.
