C-lab Answer the following questions. You may upload a handwritten file if you like, as long as it is legible. Part A: Figure numbers refer to figures in the lab procedures. Do the calculations in the units given. 1. Very briefly explain how a photogate works. 2. How far would you go if you traveled at a speed of 30 miles per hour for 3 hours? 3. What acceleration would be needed to travel the same distance in the same time as in question 2 when starting from rest? What would be your final speed? 4. Refer to Figure 3. Given a track length of 90 cm and a height difference of 18 cm, what is sin 0 5. Draw the force diagram for an object on an inclined plane (see Figure 2 in the lab manual). Attach the diagram in question 2 below. What would be the acceleration given the inclination from question 4 and g = 9.8 m/s? Part B: Attach the free body diagram from question 5 above.
