In an attempt to reduce the extraordinarily long travel times for voyaging to distant stars, some people have suggested traveling at close to the speed of light. Suppose you wish to visit the red giant star Betelgeuse, which is 430 ly away, and that you want your 20,000 kg rocket to move so fast that you age only 36 years during the round trip. Part B How much energy is needed to accelerate the rocket to this speed? Express your answer with the appropriate units. View Available Hint(s) ? xa X Xb X.10n Erocket = Value J Note: v= 0.99913 c Part C Compare this amount of energy to the total energy Eo used by the United States in the year 2015, which was roughly 1.0 x 1020 J.

A baggage handler at an airport applies a constant horizontal force with magnitude F₁ to push a box, of mass M, across a rough horizontal surface with a very small constant acceleration a. ( Figure 1) Figure 2F Submit ▾ Part B Now assume that the baggage handler pushes a third box (Figure 2) of mass m/2 so that it accelerates at a rate of 2a. How does the magnitude of the force F that the handler applies to this box compare to the magnitude of the force F₁ applied to the first box? ▸ View Available Hint(s) 0 2F Submit
