Question

1. In Newton’s 2^nd law experiment, a student measured the acceleration of the glider and the weight of the hanging mass. In this experiment, the air track was on and there was no drag force acting on the glider. The student results are shown below:

F (N)	a (m/s2)
0.100	0.100
0.200	0.250
0.300	0.450
0.400	0.600
0.500	0.800

a. Use Excel to plot the data and use the linear fit to find the slope.

b. Use your findings to determine the total mass of the system in kg.

2. In Newton’s 2^nd law experiment, a student measured the acceleration of the glider and the weight of the hanging mass. In this experiment, the air track was on and flag was installed to create a drag force. The student results are shown below:

F (N)	a (m/s2)
0.100	0.050
0.200	0.200
0.300	0.400
0.400	0.550
0.500	0.700

a. Use Excel to plot the data and use the linear fit to find the slope.

b. Use your findings to determine the total mass of the system in kg.

c. Use your findings in Question 3 to determine the drag force in N.
