A quarterback can throw a receiver a high, lazy "lob" pass or a low, quick "bullet" pass. These passes are indicated by curves 1 and 2, respectively, in the figure (Figure 1).

The lob pass is thrown with an initial speed of 21.3 m/s and its time of flight is 3.96 s . What is its launch angle?

The bullet pass is thrown with a launch angle of 22.0 ∘. What is the initial speed of this pass?

What is the time of flight of the bullet pass?

Step 1

Write the expression for launch angle, and substitute 9.8m/s2 for g, 3.96s for t, and 21.3m/s for v in the below equation to find the launch angle.

Step 2

Write the expression for range, and substitute 35m for R, 9.8m/s2 for g, and 22˚for...
