Question

Problem 71b

Answer 1

Given information

Basketball is shot from an initial height of with an initial speed of directed at an angle above the horizontal.

Step-by-step explanation

Step 1.

As the horizontal component of velocity remains constant throughout the projectile motion.

So horizontal component of velocity is    

velocity in vertical direction, when the ball enter the basket is given by equation of motion

 

Here is the vertical component of velocity when the ball enter the basket, is the vertical component of velocity when basketball is shot. is acceleration due to gravity.and is time.
