In the figures, the masses are hung from an elevator ceiling. Assume the velocity of the elevator is constant. Find the tensions in
the ropes (in N) for each case. Note that 0₁ = 35.0°, 0₂ = 55.0°, 03 = 60.0°, m₁ = 3.00 kg, and m2 = 7.00 kg. (Due to the
nature of this problem, do not use rounded intermediate values-including answers submitted in WebAssign-in your calculations.)

- You are working with a movie director and investigating a scene with a cowboy sliding off a tree limb and falling onto the saddle of a moving horse. The distance of the fall is several meters, and the calculation shows a high probability of injury to the cowboy from the stunt. Let's look at a simpler situation. Suppose the director asks you to have the cowboy step off a platform 2.55 m off the ground and land on his feet on the ground. The cowboy keeps his legs straight as he falls, but then bends at the knees as soon as he touches the ground. This allows the center of mass of his body to move through a distance of 0.660 m before his body comes to rest. (Center of mass will be formally defined in Linear Momentum and Collisions.) You assume this motion to be under constant acceleration of the center of mass of his body. To assess the degree of danger to the cowboy in this stunt, you wish to calculate the average force upward on his body from the ground, as a multiple of the cowboy's…arrow_forwardA box of mass m = 2.00 kg is released from rest at the top of an inclined plane as seen in the figure.
