A baseball player throws a ball with a mass of $0.150kg$ with a speed of $40.0 m/s$ and an angle of $30$ degrees. What is the kinetic energy of the ball when it reaches the highest point on its trajectory?
So I'm guessing this is a projectile motion - kinetic energy - energy transfer problem. I know how to get the time in which it reaches the highest point, I also know how to get $y$ of that point, but to transfer these things into kinetic energy is really difficult for me. I'm guessing that since the change on kinetic energy is equal to the work done over the object, I must get that, and I'm thinking of an Integral for the area under the curve, but I don't know how to get the function for force, or what distance should I use, maybe time? please help
