APFIVE Mechanical Energy in Projectile Motion
Two identical balls, A and B, are launched from the same height with an initial speed of v₀. Ball A is launched horizontally, while Ball B is launched at an angle θ above the horizontal. Assuming air resistance is negligible, how does the total mechanical energy of Ball A compare to that of Ball B immediately before each ball strikes the ground?
A
Ball A has greater mechanical energy
B
Ball B has greater mechanical energy
C
Cannot be determined without knowing θ
D
The mechanical energies are equal
