| Mountaineering. Figure 5.62 shows a technique called rappelling, used by mountaineers for descending vertical rock faces. The climber sits in a rope seat, and the rope slides through a friction device attached to the seat. Suppose that the rock is perfectly smooth (i.e., there is no friction) and that the climber’s feet push horizontally onto the rock. If the climber’s weight is 600.0 N, find (a) the tension in the rope and (b) the force the climber’s feet exert on the rock face. Start with a free-body diagram of the climber.

- Problems 12 and 13: An airplane of mass, m, goes into a vertical dive. The airplane's engines provide a forward thrust. Fo. Air resistance is of the form: F = bv² 12. What is the terminal velocity of the airplane? Answer 12: 13. What is the differential equation for the velocity of the airplane? Answer 13:arrow_forwardYou want to hang an object from the ceiling of an elevator that has a maximum acceleration of 4.0 m/s2. a) If you hang the object with a fishing line that supports 45 N of force, what is the maximum mass the object can have if the line is not to break? Please answer in units of kg.arrow_forward5.59 Two ropes are connected to a steel cable that supports a hanging weight (Fig. P5.59). (a) Draw a free- body diagram showing all of the forces acting at the knot that connects the two ropes to the steel cable. Based on your diagram, which of the two ropes will have the greater tension? (b) If the maxi- mum tension either rope can sustain Figure P5.59 60° 40° without breaking is 5000 N, determine the maximum value of the hanging weight that these ropes can safely support. Ignore the weight of the ropes and of the steel cable. 5.60 An adventurous archaeologist crosses between two rock cliffs by slowly going hand over hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope (Fig. P5.60). The rope will break if the tension in it exceeds 2.50 × 10* N, and our hero's mass is 90.0 kg. (a) If the angle 0 is 10.0°, what is the tension in the rope? (b) What is the smallest value 0 can have if the rope is not to break?arrow_forward

Calculate the tension in the cable supporting the elevator in newtons. T-1.695 x 10¹ T-1470 x 10 ✔Correct! The elevator continues upward at constant velocity for 8.6 s. What is the tension in the cable, in newtons, during this time? ✔Correct! The elevator experiences a negative acceleration at a rate of 0.65 m/s² for 2.7 s. What is the tension in the cable, in newtons, during this period of negative acceleration? T-13725 7-1.373x10 ✔Correct!

- When you push a 1.92-kgkg book resting on a tabletop, you have to exert a force of 2.08 NN to start the book sliding. Once it is sliding, however, you can use a force of only 1.03 NN to keep the book moving with constant speed. What is the coefficient of static friction between the book and the tabletop? Express your answer using three significant figures.arrow_forwardYou have landed on an unknown planet, Newtonia, and want to know what objects weigh there. When you push a certain tool, starting from rest, on a frictionless horizontal surface with a 12.0 N force, the tool moves 16.0 m in the first 2.00 s. You next observe that if you release this tool from rest at 10.0 m above the ground, it takes 2.58 s to reach the ground. What does the tool weigh on Newtonia, and what does it weigh on earth?arrow_forward1. A loaded elevator, 2200 kg, supported by cables that can withstand a maximum tension of 28,000 N only.
