It's your birthday, and to celebrate you're going to make your first bungee jump. you stand on a bridge 110 m above a raging river and attach a 31-m-long bungee cord to your harness. a bungee cord, for practical purposes, is just a long spring, and this cord has a spring constant of 42 n/m. assume that your mass is 80 kg. after a long hesitation, you dive off the bridge. how far are you above the water when the cord reaches its maximum elongation?
thermal energy flow from one system to other due to temperature gradient
when temperature gradient occurs it will have flow of energy from one to other
so here we can say
a calorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same temperature.
the period of a simple pendulum depends only on the length of the pendulum and the gravitational acceleration:
where l is the pendulum length and g the gravitational acceleration.
the problem says that maya and the swing form a simple pendulum, so we can use this formula to calculate the period of maya's motion, using the length of the swing (l=1.8 m):
