Baseball outfielder throws a baseball of mass 0.15 kg at a speed of 40 m/s and initial angle of 30. What is the kinetic energy of the baseball at the highest point of the trajectory? 90 J
Answers: 2
so the kinetic energy of the ball at this point is 
![\;\;\;\;\;= \frac{1}{2}(0.15\:\text{kg})[(40\:\text{m/s})\cos30]^2](/tpl/images/2609/6284/89661.png)
