A 74.0 kg tightrope walker stands at the center of a rope. The rope supports are 10 m apart and the rope sags 8.00 ∘ at each end. The tightrope walker crouches down, then leaps straight up with an acceleration of 7.80 m/s2 to catch a passing trapeze. Required:
What is the tension in the rope as he jumps?

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.
