Kinetics is a branch of dynamics that deals with the relationship between and that cause this change. 2. Newton's 2nd law states that when an ) acts on a particle, the particle will accelerate or decelerate in the direction of the force with a magnitude that is proportional to the force. 3. The...

The only force F~ acting on a body of mass m (in kg) changes in time t according to F~ (t) = (F0 sin(ωt), F0 cos(ωt)) where F0 is a constant with units of N and the greek letter ω is a constant with units of radians/s. (Technically a radian is dimensionless, but I’ve explicitly stated it to clarify the problem.) Assume all arbitrary constants that appear due to indefinite integration are zero. (a) What is the acceleration vector of...

Please help! :)
Discussion #3 1. Consider the motion of an object that can be treated as a point particle and is traveling counter-clockwise in a circle of radius R. This motion can (and will for the purposes of these discussion activities) be described and analyzed using a Cartesian (x-y) coordinate system with a spatial origin at the center of the particle's circular trajectory (the physical path its motion traces out in space). (a) Draw a diagram of the position...

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. Based on the "net force" and "total mass" approach that was used to derive equations 3,4, and 5; develop the equation for acceleration of two masses (m, and m2) hanging vertically from either side of a frictionless pulley....

1 Tasks In the class, we showed that a magnet free falling inside a copper tube experiences a braking force that slows down its fall. You are to re-explain this phenomenon using approximate yet sufficient detail math description and validate the explanation using simulation to validate the experimental observation. The tasks are: 1) Refer to the diagram on Appendix A, sketch clearly in your own interpretation of the Faraday's and Lorentz's law in the dash magenta oval in the diagram...

You see there that depending on the angle of “pull", e, three different motions can occur - the spool either rolls toward or away from the person pulling the cord or, at a critical angle of pull, does not rotate. The purpose of this exercise is to analyze this behavior using fundamental principles of mechanics. The physical system is shown in the figure and consists of two concentric spools of radius R, and R,, respectively. Cord is wrapped around the...

4. Field transformations: In the lab frame E 4 V/m, B -3y T, and a point charge q = 1C is observed to be moving with velocity v 2 m/s. a) What is the electric field E' measured in the frame of reference of q? Determine E' by ensuring that the Lorentz force applied on charge q is identical in both reference frames. b) Is this charge being accelerated or not under the influence of fields E and B? Discuss...
