- In the figure below, a climber leans out against a vertical ice wall that has negligible friction. Distance a is 0.956 m and distance L is 2.00 m. His center of mass is distance d = 0.944 m from the feet-ground contact point. If he is on the verge of sliding, what is the coefficient of static friction between feet and ground? |---Select-- v com-A man drags a 67-kg crate across the floor at a constant velocity by pulling on a strap attached to the bottom of the crate. The crate is tilted 25° above the horizontal, and the strap is inclined 61° above the horizontal. The center of gravity of the crate coincides with its geomentrical center, as indicated in the figure. Find the magnitude of the tension in the strap. 0.90 m 0.40 m 0 25⁰ 61%A factory needs to move packages from one level to another using a ramp. They want to choose a material that has a specific coefficient of friction with the packages that will be sliding down the ramp. What problem could occur if the coefficient of friction were too high?
- A 10kg book is pressed into a flat rough vertical wall with coefficient of static friction of 0.20. What minimum force is needed to stop the book from sliding down the wall? Group of answer choicesA skydiver weighing 65 kg jumps out of a helicopter hovering at a height of 3 kilometers. Assume a cross-sectional area of 0.5 square meters. After thirty seconds of free fall, the skydiver deploys the parachute and the cross-sectional area becomes 40 square meters. Reproduce the model for the skydiver in Excel or VenSim. In VenSim you may have to make At quite small in order not to throw an error. Because you reach terminal velocity relatively quickly your answer should not be particularly sensitive to the value of At you choose. What is the skydiver's terminal velocity without the parachute? meters/second What is the skydiver's terminal velocity with the parachute? meters/secondtake the x-axis along the incline (say, downhill) and the y-axis perpendicular to the incline, say upwards and solve the problem again. Then write down Newton's 2nd law in the x- and y-direction again, and find the connection between FN and FG
- **29. ssm Two vertical walls are separated by a distance of 1.5 m, as the drawing Wall 1 Wall 2 shows. Wall 1 is smooth, while wall 2 is not smooth. A uniform board is propped between them. The coefficient of static fric- tion between the board and wall 2 is 0.98. What is the length of the longest board that can be propped between the walls? -1.5 m-Two small cylindrical plastic containers with flat bottoms are placed on a turntable that has a smooth flat surface. Canister A is empty; canister B contains lead shot. Each canister is the same distance r from the center. The coefficient of static friction between the canisters and the turntable is ms. When the speed of the turntable is gradually increased,
