Hi,

The first page explains the procedure of the lab, and the second page are the questions I need help with. The last picture is my data. Please answer the questions in blue boxes.

5) Use the spring driven force meter to measure the force on your car when it is on the inclined air track: first attach the glider hook to the cart. Thread a length of sewing string around the pulley and attach one end to the cart and the other end to the force meter (Figure 1.1). When finished recording the force, remove the string from the hook attachment ) Without changing the height of the air track, ('b' in Fig. 1.2) measure the acceleration of the car. To do this: (a) Measure the distance, L, your cart will travel from the point of release to the bumper at the end of the air track (b) Release the cart from rest. (c) Using the stopwatch, measure t, the time it takes to travel the distance. (d) Use the kinematics you learned earlier in the quarter to calculate the acceleration from your measured values of L and t 7) Repeat steps 5 and 6 for at least 2 more masses. Use the chrome plated attachment masses in pairs. Increase the airflow to 4 if the cart begins to drag on the track Question 1.2 Does changing the mass affect the acceleration? Should it? 8) Uxing this height, ome trigonometry, and vector analysis calculate the theoretical acceleration on the cart from gravity (assume g--9.8 m/sec) To get to the accleration, 0 must first be determined. The angle 6 can be obtained by using b and D, where b is the height of the blodk and Dis the distance between the airtrack's legs.Once 0 has been determined, use what you know about vectors to calculate the acceleration.

Explanation / Answer

1.2 You can easily see from the data taken, that change in mass indeed affects the acceleration. It should.

1.3 No mention of b and D values.

1.4 Yes, the plot is linear. The Force is directly propotional to mass.

From the slope, acceleration comes out to be 3.8 m/s2 .

1.5 Yes, the force is directly propotional to acceleration.

Slope1 = 3.66 and Slope2 = 3.69

Values are missing to answer anything else.
