Answer:
C) 3.0 joules
Explanation:
The kinetic energy of the ball is given by:
[tex]K=\frac{1}{2}mv^2[/tex]
where
m = 0.059 kg is the mass of the ball
v is its speed
At the beginning, v = 26 m/s, so the initial kinetic energy is
[tex]K=\frac{1}{2}(0.059 kg)(26 m/s)^2=20 J[/tex]
after the rebound, v = 24 m/s, so the final kinetic energy is
[tex]K=\frac{1}{2}(0.059 kg)(24 m/s)^2=17 J[/tex]
So, the energy that was lost is
[tex]E=20 J-17 J=3 J[/tex]
