DATA You are a scientist studying small aerosol particles that are contained in a vacuum chamber. The particles carry a net charge, and you use a uniform electric field to exert a constant force of 8.00 × 10−14 N on one of them. That particle moves in the direction of the exerted force. Your instruments measure the acceleration of the particle as a function of its speed ʋ. The table gives the results of your measurements for this particular particle.
(a) Graph your data so that the data points are well fit by a straight line. Use the slope of this line to calculate the mass m of the particle. (b) What magnitude of acceleration does the exerted force produce if the speed of the particle is 100 m/s?

- An object is moving between two points on a circle with radius R. The object can only move along the circle. The function F is the path length travelled between two points on the circle. a. Assume that the position of the object along the circle is described by an angle θ with respect to the center of the circle and the x-axis. Is this angle a minimum set of generalized coordinates for this problem? b. Assume that the position of the object along the circle is described by two Cartesian coordinates x and y, where the origin of the coordinate system is the center of the circle. Are these coordinates a minimum set of generalized coordinates for this problem? c. What would be the holonomic constraint for the two Cartesian coordinates x and y for the motion around the circle? d.
