1) What is the formula that describes how the acceleration of an object down an inclined plane? Make sure that your answer depends on the angle the incline is elevated (with respect to the horizontal). Note, after you learn about forces and inclined planes, you should try deriving this yourself.

4) In the position formula, x(t)=Qt² -3Rt +S, what is the value of the velocity at time t = 2
5) Two distances are measured for the same object. The first is 53.8±0.4cm; and the second is
41.5±0.6cm, are they in agreement? Show your work. (See analysis section 3.b - show your
work.)
