Question: During a wrestling match, a 110 kg wrestler briefly stands on one hand during a maneuver designed to perplex his already moribund adversary.
l = 39 cmr = 2.3 cmm = 110 kg
By how much does the upper arm bone shorten in length in meters? The bone can be represented by a uniform rod 39 cm in length and 2.3 cm in radius with a Young's modulus of 1.6 × 1010N/m2.

A 1200 crate slides 15 down a ramp that makes an angle of 30 with the horizontal. If crate slides at a constant speed, how much thermal energy is created?
Water is flowing in a cylindrical pipe of varying circular cross-sectional area, and at all points the water completely fills the pipe. What is the radius of the pipe at this point
a force has a strength of 87 n and makes an angle of 21 degrees with respect to the positive x axis in the x-y plane.
