A simple pendulum has a mass 7.2 kg and a length 2.27 meters. How much initial velocity v in m/s must be given to the mass with the pendulum if it is initially hanging vertically downward in order for it to later reach an angle of 56.8 degrees

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.
