The question is basically:
You are on top of a edge that is 32.5m high and you drop 1 ball, moments later you throw a 2nd ball at the initial speed of 11 m/s. Which ball has a greater increase in speed, or is the increase the same? and prove it with a calculation.
I started out with the x=x0 + v0t = .5at^2
For the first ball I got the time to be 2.57 s and for the second ball i got the time to be 1.68 s.
i proceed to try and work it out finding the velocity by using the v = v0 + at. and got 25.21 m/s^2 for the first ball and 27.53 m/s^2 for the 2nd.
this is where i have the problem. is the increase in the speed talking about acceleration? because if it is acceleration then shouldnt both ball have the same increase in speed because gravity is working on both of them equally?
