In the figure a 57 kg rock climber is in a lie-back climb along a fissure, with hands pulling on one side of the fissure and feet pressed against the opposite side. The fissure has width w = 0.15 m, and the center of mass of the climber is a horizontal distance d = 0.30 m from the fissure. The coefficient of static friction between hands and rock is μ1 = 0.35, and between boots and rock it is μ2 = 1.30. The climber adjusts the vertical distance h between hands and feet until the (identical) pull by the hands and push by the feet is the least that keeps him from slipping down the fissure. (He is on the verge of sliding.)
(a) What is the least horizontal pull by the hands and push by the feet that will keep the climber stable? (b) What is the value of h?
A 84 kg athlete has his center of gravity 1.19 meters above the ground in a standing position (height that person comes off the ground during a jump). During a squat jump, he crouches down so that his centre of gravity is 0.75 meters above the ground. As he jumps, he exerts an average force of 1280 Newtons against the ground. You can think of this average exerted force as the average normal force or average ground reaction force being read by the force plate during the takeoff phase of the jump.
a) Determine the maximum height that the person’s center of mass will reach in meters using the concepts of Work and Energy.
b) What is magnitude of the person’s vertical velocity in m/s just as his feet leave the ground during the maximal vertical jump?
A 13-kg dog jumps up in the air to catch a ball. The dog's center of mass is normally 0.20 m above the ground, and he is 0.50 m long. The lowest he can get his center of mass is 0.10 m above the ground, and the highest he can get it before he can no longer push against the ground is 0.40 m
If the maximum force the dog can exert on the ground in pushing off is 2.1 times the gravitational force Earth exerts on him, how high can he jump?
