Question1
Batman, who’s mass is 110 kg, is holding on to free end of a 5.08 m rope, other end of which is fixed to a tree limb above. He is able to get the rope in motion as only Batman knows how; eventually getting it to swing enough that he can reach a ledge when the rope makes a 54.3? angle with vertical.
An acceleration of gravity is 9.8 m/s2.
How much work was done against force of gravity in this maneuver?
Question2
Consider an alcohol and a mercury thermometer that read exactly 0°C at the ice point and 100°C at the steam point. The distance between two points is divided into 100 equal parts in both thermometers. Do you think these thermometers will give exactly the same reading at a temperature of, say, 60°C? Elucidate.
