Answer:
Final velocity, v = 1.41 m/s.
Explanation:
It is given that,
Initial velocity of the basketball, u = 4 m/s
Acceleration of the ball, a = -0.5 m/s² (as it slows down)
We need to find the velocity of the basketball after rolling for 14 m. It is a concept of equation of motion in kinematics. Using third equation of motion as :
[tex]v^2=u^2+2ad[/tex]
v is final velocity
[tex]v^2=(4)^2+2\times (-0.5)\times 14\\\\v=\sqrt 2\ m/s\\\\v=1.41\ m/s[/tex]
So, the final velocity of the basketball is 1.41 m/s.
