On one occasion during the current mission, James Bond throws a stone from the top of a building upward at an angle of 30.0° to the horizontal with an initial speed of 20.0 m/s as shown in the figure. The height from which the stone is thrown is 45.0 m above the ground. Mr. Bond's friend, Dr. Madeleine Swann, is going to compute the speed of the stone at the time instant t = 3.00 s. What is the speed of the stone at the time instant t = 3.00 s? (A) 26.0 m/s (B) 37.0 m/s (C) 45.0 m/s (D) 52.5 m/s (E) 68.5 m/s 45.0 m y v₂ = 20.0 m/s 30.0⁰ x
