An outfielder throws a 1.92 kg baseball at a
speed of 64 m/s and an initial angle of 19.7.
What is the kinetic energy of the ball at the
highest point of its motion?
Answer in units of J

amistre64 · Answer

hmm, its either 1/2  mv^2,  or 0 depending on how your defining it

amistre64 · Answer

it total KE is 0 for up and down;  + 1/2 mv^2 for it forward KE

Oh ya, I forgot about it being zero at the highest point maybe it is that if not I'd just have to solve for velocity?

amistre64 · Answer

the energy of it movng forward might need to be accounted for.

but yeah, at its highest point, it energy downward is all potential

amistre64 · Answer

$$\frac12(1.92)(64\cos(19.7))^2$$
is what im thinking at best
