Mechanical Energy in Projectile Motion
Two identical balls A and B are thrown from the same height. Ball A is thrown horizontally with speed v₀, while ball B is thrown at an angle θ above horizontal with the same speed v₀. Neglecting air resistance, how do their mechanical energies compare just before hitting the ground?
A
Cannot be determined without knowing θ
B
The mechanical energies are equal
C
Ball B has greater mechanical energy
D
Ball A has greater mechanical energy
