Michael (mass of approximately 60 kg) does push-ups by applying a force to elevate its center-of-mass by 20 cm in order to do 850 Joule of work. If the man does all this work in 5 seconds, then determine its power.
An escalator is used to move 15 passengers every minute from the first floor of a department store to the second. The second floor is located 6 meters above the first floor. The average passenger's mass is 52 kg. Determine the power requirement of the escalator in order to move this number of passengers in this amount of time. *

Calculate the percent by volume of a 120-mL solution that contains 15.0 mL of surcose (C12H22O11)
- A nitrogen molecule can be thought of as two point masses (m of each = 14u, where u = 1.67 x 10-27 kg) separated by a distance of 1.3 x 10-10 m. In air at room temperature the average rotational kinetic energy of such a molecule is about 4.0 x 10-21 J. Find the moment of inertia of such a molecule about its center of mass, and its speed of rotation in revolutions per second.
