Q2- An adventurous archeologist (m = 86.5 kg) tries to cross a river by swinging from a vine. The vine is 12.0 m long, and his speed at the bottom of the swing is 7.95 m/s. The archeologist doesn't know that the vine has a breaking strength of 1,000 N. Does he make it safely across the river without falling in? YES OR NO
Explanation / Answer
I do not accept the statement. The reason behind this is the astronauts feel weightless because of their free fall and they are orbiting means they must be in gravitational pull. Another important thing is that if there is no gravity they leave the space with a straight line motion.
