On one occasion during the current mission, James Bond throws a stone from the top of a building upward at an angle of 0₁ = 30.0° to the horizontal with an initial speed of v = 40.0 m/s as shown in the figure. The height from which the stone is thrown is O 45.0 m above the ground. Assume that there is no air resistance. Mr. Bond's friend, Dr. Madeleine Swann, is going to use an energy approach to compute the speed of the stone just before it hits the ground. What is the speed of the stone just before it hits the ground? (A) 25.5 m/s (B) 49.8 m/s (C) 32.6 m/s (D) 58.7 m/s (E) 63.5 m/s 45.0 m Vi x Hint: Consider conservation of the mechanical energy of the system of the stone and the Earth.
