5. A basketball player is standing on the floor 14.5 m away from the basket. The height of the basket is 3.10 m, and he shoots the ball at 50.0° with the horizontal from a height of 1.90 m. At what speed must the player shoot the ball so that it goes through the hoop without striking the backboard? m/s

Expert Solution
Introduction:

Projectile motion and equation of motion:

When an object is thrown at angle θ from the horizontal surface, object follows a curved path before reaching to ground.

The total time of flight (t in s) is the time during which it remains in the projectile motion.

Object has two components of initial velocities: First component is horizontal velocity (vx)and second component is vertical velocity (vy).

  • vx will remain constant through out it's flight time (t)= v cos θ
  • vy is the initial velocity and final velocity can be calculated based on constant acceleration due to gravity in vertical direction and for that equation of motion is used.

Equation of motion:

It is used to establish relationship between distance travelled, initial & final velocities during the time (t) travelled under constant acceleration.

Mathematically,

v= u ± atv2± u2= 2 a ss= u t ±12 a t2
