6. (4 pts) Two people start at the same place and walk around a circular lake in opposite directions. One has an angular speed of 4.0 x 10-3 rad/s, while the other has an angular speed of 6.0 x 10-rad/s. How long will it be before they meet? End Start
Myron Corporation is sponsoring a walking race at its company outing. Leona Jackson and Sam Peterson love to walk. Leona walks at the rate of 8 miles per hour. Sam walks at the rate of 9 miles per hour. Assume they start walking from the same place and walk in a straight line. Sam starts 34 hours after Leona. Answer the questions that follow. Hint: Distance = Rate × Time. a. How many miles would each have walked? (Do not round...
Two runners are running a 2 kilometre race on a circular 400 meter track. The ratio of the speed is 3:2. The runner run in the opposite directions, beginning at the same time at the same start of the track. They both stop when the first person finishes. The number of times they pass each other is ?
7. (2 pts) Two loops, one circular with radius a and current Ic and the other an equilateral triangle with side 2a and current It, are a distance r apart as shown in the diagram (centers of the loops are on the same axis). The direction of the current in the triangle i:s clockwise when viewed from the left end of the axis looking down the axis (to the right) The direction of the current in the circle is opposite...
4. Two toy remote-controlled cars start from the same position, O, at time t-0. One car, C ,travels north at 4 m/s, while the other, C2, travels west at 2 m/s. (a) After two seconds, compute the rate of change of the distance between Ci and Cz. Draw a diagram to help you answer this question and the next and clearly state the units. Simplify your answer as much as possible. (7 pts.) (b) After two seconds find the rate...
