2. A SOLID sphere is dropped from rest as shown in the figure. The mass, rolls without sliding and after leaving the table top follows a projectile path towards the ground.(25 points)Let the little height, h = 80 cm and the big height, H = 1.5 meters. Find the value of ”x” Remember that the solid sphere has a moment of inertia, I = 2/5∗m∗R2. You can also take gravity, g= 10m/s^2

An inclined plane wrapped around a metal shaft is a a. lever b. screw c. pulley d. wedge

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

An isotope undergoes radioactive decay by emitting radiation that has a –1 charge. what other characteristic does the radiation have?
