Question
In the opening sequence of the movie, Raiders of the Lost Ark, the intrepid explorer Indiana Jones deftly swipes a golden idol from a Mayan temple, instantly replacing it with a bag of sand of the same size to neutralize the ancient weight-based booby trap protecting it. (a) The density of gold is 19,300 kg/m3. If the idol's mass is 11.3 kg and it is solid gold, calculate its volume. (b) The density of silica sand is 1220 kg/m3. What is the mass of a sandbag of equal volume? (c) Is the scene realistic?Explanation / Answer
(a) m = 11.3 kg
volume = 11.3 / 19300
= 5.8549 * 10^-4 m^3
= 585.49 cm^3
(b) mass of sandbag = 1220 * 5.8549 * 10^4
= 0.714 kg
(c) No,since the masses differ greatly!
