6. When the system is in motion how does the acceleration of the hanger compare to the acceleration of the cart? (a) The acceleration of the hanger is equal to the acceleration of the cart. (b) The acceleration of the hanger is less than the acceleration of the cart. (c) The acceleration of the hanger is greater than the acceleration of the cart. (d) It depends on the trial. 7.

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...

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. Applying Newton's second law to a setup like...

A 3.50-kg block on a smooth tabletop is attached by a string to a hanging block of mass 2.80 kg, as shown in the figure. The blocks are released from rest and allowed to move freely Part A Is the tension in the string greater than, less than, or equal to the weight of the hanging mass? Part B Find the acceleration of the blocks. Part C Find the tension in the string.

[This experiment used a weight at the end of a string along a track. The track had a cart that was attached to the string. Different weights were put at the end of the string that was hanging over the ledge. Multiple trials were done. We took times of how long it took the cart to travel from point A to point B as it was pulled by the weight at the end of the string. Additional trials placed weights...

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) Rita is in an elevator that is moving at a constant velocity downward. If the elevator now experiences an acceleration so that it speeds up, the normal force Rita experiences A) becomes greater than her weight. B) remains equal to her weight. C) becomes less than her weight, but not equal to zero. D) becomes zero. E) cannot be determined without more information. 11) A rope connects object A (mass 4m) with object B (mass m). (Object A is...

3. For experiment A, use equations 1&3 to develop a general equation for the value of tension (T) based on the values of the two masses. You will need this later to answer lab question (4), so write it in now. 4.
