A movie scene reads as : " Katrina is thrown off a cliff by villains. Salman has to save her but he jumps one second later than when she falls." He still saves her since his weight is much more than that of Katrina. Assuming that there is no air resistance, is the scene logically possible ?

Solution

The correct option is B
False

Whenever two bodies, which start together, are in free fall, irrespective of their weight, they have the same acceleration (g) and hence fall on the earth at the same time. But in the movie scene, Katrina starts her free fall one second earlier than Salman. Also, since there is no air resistance, we can say that the given scene is physically impossible since Katrina will fall one second before Salman.

Q. A student determined to test the law of gravity for himself walks off a sky scraper 320 m high with a stopwatch in hand and starts his free fall (zero initial velocity). 5 second later, superman arrives at the scene and dives off the roof to save the student.
