A body of mass m is thrown at an angle theta with the horizontal. At the highest point, its kinetic energy is:
AZero
B1/2 mv^2
C1/2 mv^2 cos^2(theta)
D1/2 mv^2 sin^2(theta)
✓ Correct Answer: C — 1/2 mv^2 cos^2(theta)
At the highest point, the vertical velocity is zero, only horizontal velocity v*cos(theta) remains.
