If it is hand written, kindly write legibly. Thanks
For an Atwood experiment how could you vary a total mass and keep net force constant or vary net force and keep total mass constant
Fill in the table by calculating the dilated time given the velocity of the object.
Then, graph speed versus dilated time in the graphing section below the table.

- Draw a free-body diagram and write Newton’s second law of motion for the forces and accelerations experienced by a pendulum bob of mass m swinging under the influence of gravity, g, when it is at the very bottom of its swing (θ=0°). There are two force terms that need to be considered (be careful about the direction of those forces) and only one acceleration term. Consult your unit on circular motion for this. Finally, using this equation, derive an expression for the velocity of the bob at that point.arrow_forwardIn a lab frame of reference, an observer finds Newton’s second law is valid in the form. Show that Newton’s second law is not valid in a reference frame moving past the laboratory frame of Problem 1 with a constant acceleration a1.
