Tutorial Section 1.1 - Review of position and velocity Note: Before doing the tutorial each week, it is important to read the explanation and equipment sections. If you haven't already, do this reading for tutorial 1. 1. Defining a coordinate system. Imagine you were told that an object begins at the top of a ramp and moves down the ramp with a speed of 3mph. The incline angle of the ramp (with the horizontal) is 0. a. Different coordinate systems are chosen in the first two boxes. Draw a third, different coordinate system in the third box. 2. In the box beneath each drawing, write the equation for the velocity vector for the given coordinate system using i-hat and j-hat notation (1 , j ). coordinate system choice 1 coordinate system choice 2 coordinate system choice 3 +V +X +X V= +3mph i V= i+ V = i + Checkpoint. Please continue working. 3. Since velocity is a vector, the definition of velocity illustrates that position must also be a vector. Imagine a ball is shot horizontally off the ramp and is currently at the location shown. Using the coordinate system given, draw the position vector for the O object at this location and label the vector using the notation described in the explanations (section 1)
