Atoy gun uses a spring with a force constant of 285 n/m to propel a 9.5-g steel ball. assuming the spring is compressed 7.6 cm and friction is negligible, answer the following questions: (a) how much force is needed to compress the spring? (b) to what maximum height can the ball be shot? (c) at what angles above the horizontal may a child aim to hit a target 3.00 m away at the same height as the gun? (d) what is the gun's maximum range on level ground?

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.
