A loaded elevator with very worn cables has a total mass of 2000kg , and the cables can withstand a maximum tension of 2.80×10^4N Part A Draw the free-body force diagram for the elevator.(Assume that the elevator is accelerating upward.) Draw the force vectors with their tails at the dot. The orientation of your vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded.
Part B Apply Newton's second law to the elevator and find the maximum upward acceleration for the elevator if the cables are not to break? Please Help Guys.
A 800kg car pushes a 1800kg truck that has a dead battery. When the driver steps on the accelerator, What is the magnitude of the force of the car on the truck
moves through its horizontal position at (B) and up to (C) where it stops with 2 = 109.0o, and then falls back down. Friction at the pivot is negligible. Compute the speed of the CM at (B).
