Q. The sketch shows a painting staging in mechanical equilibrium. The person in the middle weighs 265 N, and the tensions in each rope are 200 N. What is the weight of the staging?
Q. At one instant a bicyclist is 40.0m due east of a park's flagpole, going due south with a speed of 10.0m/s. Then 30.0s later, the cyclist is 40.0m due north of the flagpole, going due east with a speed of 10.0 m/s. For the cyclist in the 30.0s interval, what are the (a) magnitude and (b) direction of the displacement, the (c) magnitude and(d) direction of the average velocity and the (e) magnitude and (f) direction of the average acceleration?
