SA13. A basketball player throws a desperation shot at the buzzer from the backcourt 1.0 second before the game ended with the score tied. If the ball was released at a velocity of 12.0 m/s at an angle of 38O and if the release was made at the same level as the basket from a distance of 14.2 m, did he score? Why?

A ball is dropped from rest and feels air resistance as it falls. Which of the graphs in Fig. Q5.26 best represents its vertical
velocity component as a function of time?
