2. A 0.5 kg cube connected to a light spring for which the force constant is 20 N/m oscillates on a horizontal, frictionless track with an amplitude of 6 cm. Calculate the velocity of the cube when the displacement is 2 cm. 3. A stone is thrown from the top of a building upward at an angle of 30° to the horizontal and with an initial speed of 10 m/sec. If the height of the building is 45 m, what is the velocity of the stone as it strikes the ground?
