You have experienced a skiing accident and are trapped at the bottom of a ravine as shown in the figure below. Rescuers h A slope of length d makes an angle of 0 with respect to the horizontal. You are on the ground at the bottom of the slope, and the rescuers are at the top of the slope. The top of the slope is a height h above the ground. During the accident, you cut your leg and it is bleeding continuously. Rescuers have arrived at the top of the ravine. The slope down to you is very steep; it is at 0 = 71.0⁰ with respect to the horizontal. The rescuers will require safety equipment to climb down to you. They have secured a post at the top of the ravine d= 7.95 m from you, measured along the slope, and are going to send a medic down a rope tied to the post. Unfortunately, a critical and unique carabiner (a type of clip used in mountain climbing) was accidentally dropped and has slid down the slope to you. The rescuers do not have another carabiner that will work, and you don't have time for them to go back to headquarters and get another one, because of the bleeding in your leg. The rescuers call for you to project the carabiner up the hill so that it slides all the way from you to them. (a) The snow on the slope is essentially frictionless. How fast must you project it (in m/s)? (Round your answer to at least one decimal place.) m/s (b) Suppose that there is friction in the slope and that the coefficient of kinetic friction between the carabiner and the snow is 0.200. In this case, how fast must you project it (in m/s)? m/s You have experienced a skiing accident and are trapped at the bottom of a ravine as shown in the figure below.
