Abaseball slugger hits a pitch and watches the ball fly into the bleachers for a home run, landing h = 9.5 m higher than it was struck. when visiting with the fan that caught the ball, he learned the ball was moving with final velocity vf = 30.15 m/s at an angle θf = 29° below horizontal when caught. assume the ball encountered no air resistance, and use a cartesian coordinate system with the origin located at the ball's initial position.

The ball's position can get of the initial angle when leave the bat and velocity magnitud.

θ = 35,1

v = 36,5

Explanation:

θf= 29

h= 9,5 m

vf= 30,15

Now as you know the vector in 'y' can be related with Tan function

So, the initial velocity in 'y' can be resolved:

Finally the velocity is going to be:

θ

θ

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
