A player passes a basketball to another player who catches it at the same level from which it was thrown. The initial speed of the ball is 8.1 m/s , and it travels a distance of 4.2 m .


What was the initial direction of the ball?

What was its time of flight?


Expert Answer

Step 1

Consider that the basketball is thrown with an angle θ from the horizontal axis. The initial speed of the ball has two components; one along the horizontal axis and one along the vertical axis. Hence, the components of speed are given by:
