duction In this experiment, we will investigate some properties of projectile motion. The basic physics is simple: a ball rolls down an incline which has been placed on top of a table. When it reaches the bottom of the incline, it proceeds to roll off the edge of the table and falls "freely" solely under the influence of gravity. This motion is two-dimensional. If we refer to the horizontal direction as the x-direction and the vertical direction as the y-direction, we have two independent position equations of motion for the ball upon its leaving the table: In these equations, is the ball's (constant, horizontal) velocity as it leaves the table and g is the acceleration due to gravity. At the surface of the Earth, g is a constant . In order for these equations to make sense, you will have to determine where the origin of the coordinate system is for the simulation. Questions and Analysis 1. Plot vs. v0. It should be linear (or close). Is it? Which equation above ((3.1) or (3.2)) does this graph correspond to? 2. Calculate the slope of the line. 3. What are the units of the slope? a. meters (m)b. seconds (s)c. meters/second (m/s) 4. What is the significance of this number (the slope) in terms of what's happening in the experiment? 5. Can you use this value to calculate the value of g? If so, what do you obtain? (Hint: you will need to find an equation for g)
