6. 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 below. (a) The
lob pass is thrown with an initial speed of 21.5m/s and its time of flight is 3.97s. What is
the launch angle? (b) The bullet pass is thrown with a launch angle of 25.0°. What is the
initial speed of this pass? (c) What is the time of flight of the bullet pass?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

This did i unseated, sorry
