Problem 3, Taylor 7.41 p.288 A bead of mass m is sliding without friction on a wire that is bent in the shape of a parabola (see Figure 3, below) and is being spun with constant angular velocity w about its vertical axis 2 Figure 7.17 Taylor CLASSICAL MECHANICS OUniversity Science Books, all rights reserved Figure 3: Bead on a spinning parabolic wire Use cylindrical polar coordinates and let the equation of the parabola be kρ2 a) Write down the Lagrangian in terms of p as the generalized coordinate. b) Find the equation of motion of the bead and determine whether there are positions of equilibrium, that is values of ρ at which the bead can remain fixed without sliding up or down the spinning wire c) Discuss the stability of any equilibrium positions you find.

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite is first released from a space shuttle, which is in a circular orbit at an altitude of 185 mi, and is then propelled by an upper-stage booster to its final altitude. As the satellite passes through A, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. The booster is again fired at Bto insert the satellite into a geosynchronous orbit. The second firing increases the speed of the satellite by 4830 ft/s. INS Rani Determine the increase in speed resulting from the first firing at A. The increase in speed resulting from the first firing at Ais ft/s.

5. Evaluate the following integrals: a. Sg(+ b)8(t – t)dt -00 b. $(2t? + 8)8(2 – t)dt c. S. cos (2x – 1)]8(3x – 2)dx - Hint: 8(x) is located at x = 0. For example, 8(1-t) is located at 1 – t=0, that is, at t = 1, and so on.

Point charge q1 = -5.00 nC is on the x-axis at x = -0.400 m. Point P is on the x-axis at x=0.200m. Point charge q2 is at the origin. What are the sign and magnitude of q2 if the resultant electric field at point P is zero? Express your answer in nanocoulombs.
