Lab Activity: Newton's Second Law The goal of this exercise is to examine a system of connected objects and verify that Newton's second law correctly describes the motion. Work through the following sections answering all questions and filling in all blanks and charts directly on these sheets. Make sure that you follow the instructions carefully. Apparatus The setup consists of a cart on a track, a smart pulley, a hanger, various masses, and a computer. The motion of the cart...

A group of students performing Newton's Second Law experiment generated the graph shown below from their data. Which of the following statements is true regardingthe trustworthiness of the data? (Select all that apply.)Friction would cause the plot to be shifted upward such that the y-intercept is positive. Therefore thenegative y-intercept indicates incorrect data.The track was not level and the cart went downhill during the experiment, causing the cart to accelerate in theforward direction even when the hanging mass was zero.The...

1a. A frictionless cart of mass Mc is seated on a flat frictionless track. The cart is attached by a string to a hanging mass mh. The cart, initially at rest, is pulled to the right by a wire with constant tension T, on a frictionless table. Draw the free-body diagram only for the cart. b. Write newtons second law for the horizontal axis, for the cart of mass Mc. c. draw the free-body diagram for the hanging mass mh...

The sum of the forces on an object is directly proportional to
the mass of the object and directly proportional to the
acceleration of the object. The second law is expressed by the
equation: (1) F=ma
If the mass is in kg and the acceleration in m/s2,
then the force is in Newtons.
In (1), F is the net applied force, m is the mass of the object
on which the force is applied, and a is the acceleration of...

2. Suppose you did two separate trials with the same mass on both the cart and the hanger, but the software reported different values for b. Should one of the runs be rejected? (a) The one with the larger value of b should be rejected. (b) The one with the smaller value of b should be rejected. (c) Neither should be rejected, the value of b has no effect on our results.

2. Atwood's Table with Two Hanging Masses You have table of width L, masses m1, m2, and m3, two frictionless pulleys, and ideal string. Placing m2 on the table, you attach a bit of string to mass m1 the left pulley, to the left side of m2. Similarly, you hang mass m3 from the right side of m2 using the pulley on the right side of the table. The coefficient of friction of the table is mu. The acceleration of...

In lab, you used an Atwood's Machine to verify Newton's Second Law of Motion. The acceleration of the masses in an Atwood's machine is given by a = (m_1 - m_2)g/m_1 +m_2, where m_1 represents the greater mass and g is the acceleration due to gravity. Use kinematics to calculate the final velocity of the masses after they have moved through a distance h. Assume that both masses are initially at rest. Use a work-energy approach to verify your answer...
A mass m, = 6.9 kg rests on a frictionless table. It is connected by a massless and frictionless pulley to a second mass m2 =2.4 kg that hangs freely.
A mass m, = 6.9 kg rests on a frictionless table. It is connected by a massless and frictionless pulley to a second mass m2 =2.4 kg that hangs freely. 1) What is the magnitude of the acceleration of block 1? 2) What is the tension in the string?3) Now the table is tilted at an angle of 9= 79' with respect to the vertical. Find the magnitude of the new acceleration of block 1. 4) At what “critical" angle will the blocks NOT...
