Are the following correct?
HYPOTHESIS A: Distance is directly proportional to the square of time if acceleration is uniform.
HYPOTHESIS B: Rate of acceleration is proportional to incline of ramp.
HYPOTHESIS C: Objects will reach the same speed from a given height regardless of incline.

Those were all Galileo's hypothesises...today we did a lab and experimented whether they were correct or not...are they all correct because our experimental data was extremely bad.

Thanks

I really don't want to be mean but the rules (#2) state that no homework threads should be created in the General Discussion. Try this or this sub-forum. Good luck

Are they? Think about it.

Part A: You have the equation:

x = xo + vot + 1/2at^2

xo and vot are out, considering they are your starting points and should be o.

x = 1/2at^2.

x = distance. Is part A true?

Part B: You need to draw a force body diagram.

F = MA; in the y direction there's no acceleration but in the x direction there is. So do an {Fx = MA

Part C: Is it true? Does mass play a role in the end? Do the basic algebra, see what cancels out. However, I will say something does cancel out.
