Sketch (schematically) the Maxwell-Boltzmann translational energy distribution and label the energy axis as best you can in any energy units that you choose. I am looking for a graph. You can sketch it by hand and scan or take a digital photo if you wish, and I'd like to know where the Maximum of the curve is on the X-axis (
Using planck's energy density per unit frequency formula. r(x)= x^3 / e^x -1. Plot r(x) from excel spread sheet and determine its maximum. I need help in using excel to graph this in order to find the maximum. Then based on the maximum I am supposed to determine planck's constant.
A circus perfomer swings down on a trapeze from a height of 18m (starting from base ground). He picks up an assistant standing on the floor, and just reaches a platform of height h, depositing the assistant on the platform as they reach zero speed together.

The ball has a weight of 15 lb and is fixed to a rod having a negligible mass. If it is released from rest when theta = 0 deg., determine the angle theta at which the compressive force in the rod becomes zero (see attachment for an illustration) answer should be 48.2 deg. Not sure how to get there though.
The collar has a weight of 8lb. If it is released from rest at a height of h= 2ft from the top of the uncompressed spring, determine the speed of the collar after it falls and compresses the spring 0.3ft. See the attached file for the solution.
The Great Sandini is a circus performer with mass 60.0 kg who is shot from a cannon (actually a spring gun). You don't find many men of his caliber, so you help him design a new gun. This new gun has a very large spring with a very small mass and a force constant of 1300 N/m that he will compress with a force of 5000 N. The insi
Ice-hockey star Wayne Gretzky is skating at 13.0 m/s toward a defender, who in turn is skating at 5.0 m/s toward Gretzky. Gretzky's weight is 756 N; that of the defender is 900 N. Immediately after the collision, Gretzky is moving at 1.5 m/s in his original direction. You can ignore external horizontal forces applied by the ice
A 2.5 kg block collides with a horizontal spring of negligible mass and spring constant. k=320 N/m. The block compress the spring by 8.5 cm from its rest position. How fast was the block going when it hit the spring if the frictional coefficient between the block and the horizontal surface is 0.40?

Show that the time rate of change of mechanical energy for a damped, undriven oscillator is given by dE/dt = -bv^2 and hence is always negative. Proceed as follows: Differentiate the expression for the mechanical energy of as oscillator, E = 1/2mv^2 + 1/2kx^2 and use the following equation: -kx -b dx/dt = m d^2x/dx^2

A 3.2 kg block is hanging stationary from the end of a vertical spring that is attached to the ceiling. The elastic potential energy of this spring/mass system is 1.6 J. What is the elastic potential energy of the system when the 3.2 kg block is replaced by a 5.6 kg block?
The scheme presents two blocks: The first, Block A, is on a table. Block A is attached to an end of a string. At the end of the table, there is a pulley; the string passes by this pulley, then becomes vertical. At the other end of this string (end of this vertical string) there is Block B. So Block A is attached to Block B by
