If an object is not accelerating what can you determine about the sum of all the forces on the object?

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

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.

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?
