Three joggers are running along straight lines as follows: jogger a, with a mass of 55.2kg, is traveling along the line y=6.00m at 3.45 m/s in the positive x-direction. jogger b, with a mass of 62.4kg, is traveling at 4.23 m/s along the line x=3.00m in the positive y-direction. jogger c, with a mass of 72.1kg, is traveling at 4.75 m/s along the line x=-5.00m in the negative y-direction. what is the total counterclockwise angular momentum of the three joggers about the origin?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
