Answer:
The tennis ball has more kinetic energy
Explanation:
Recall the formula for kinetic energy: [tex]K=\frac{1}{2} \,m\,v^2[/tex] , so we can estimate it for each case and compare the results:
For the baseball:
[tex]K=\frac{1}{2} \,m\,v^2\\K=\frac{1}{2} \,0.14\,(41)^2\,\,J\\K=117.67\,\,J[/tex]
For the tennis ball:
[tex]K=\frac{1}{2} \,m\,v^2\\K=\frac{1}{2} \,0.058\,(67)^2\,\,J\\K=130.181\,\,J[/tex]
Therefore, the tennis ball has more kinetic energy
