A stone is projected with kinetic energy E, making an angle with the horizontal. When it reaches a highest point, its kinetic energy is
Options
- AE^2 ^2
- BE
- CE ^2
- DE
Correct answer
C. E ^2
Step-by-step solution
Initial kinetic energy: E = 1 2 m v₀^2 For projection angle , the velocity at the highest point retains only the horizontal component: v_h = v₀ . The kinetic energy at this point becomes: E_h = 1 2 m v_h^2 = 1 2 m (v₀ )^2 = 1 2 m v₀^2 ^2 = E ^2 Final answer: C
