An elevator with a mass of 4850kg is to be designed so that the max acceleration is 0.068g. What are the maximum and minimum forces the motor should exert on the supporting cable?  I know the answers are rounded to 50800N (max) and 44300N(min), but I have no clue how to get those numbers.

PLEASE ANSWER ONLY IF YOU ARE SURE IT IS RIGHT! PLEASE BE NEAT AND DO ASAP!

A tightrope walker is standing still with one foot on the tightrope as shown in the figure below. If the tightrope walker weighs 139 pounds, find the magnitudes of the tension in the rope toward each end of the rope. Assume E = 75.5° and F = 83.5°. (Round each answer to the nearest whole number.) |CB|  =  lb |CA|  =  lb

Hi, I really appreciate you taking the time to help me out! John places a coin on a horizontal turntable with a rubber surface. The coin is 28 cm from the center of the circular table. He notices that the coin just begins to slip when the table rotates at 45 rpm (revolutions per minute). What is the coefficient of static friction between the coin and turntable?

A uniform plank of length 2.00 m and mass 26.0 kg is supported by three ropes, as indicated by the blue vectors in the figure below. Find the tension in each rope when a 710–N person is d = 0.500 m from the left end. Answer the 3 boxes below:

A gymnast rises onto her toes, as shown in the picture on the right. The floor pushes up on the ball of her foot with a force of N=313 N. If 0=56.0°, what are FH the forces in her heel (TH) and ankle joint (T), and what is the angle o? Answers: TH=481 N; T,=761 N; b=20.7° N, 0. 4.25 cm 9.66 cm 5.

A speedboat with a mass of 545 kg545 kg (including the driver) is tethered to a fixed buoy by a strong 32.7 m32.7 m cable. The boat's owner loves high speed, but does not really want to go anywhere. So the owner revs up the boat's engine, makes a lot of noise, and runs the boat in circles around the buoy with the cable supplying all the necessary centripetal force. When the tension of the cable is steady at 13700 N,13700 N, with what force is the boat's engine pushing the boat? Different physics textbooks treat drag force somewhat differently and use different formulas. For the present purpose, take the water's drag force on the boat to be (450 kg/m)×?2,(450 kg/m)×v2, where ?v denotes the boat's speed. Ignore any drag force on the cable.

A speedboat with a mass of 505 kg (including the driver) is tethered to a fixed buoy by a strong 29.7 m cable. The boat's owner loves high speed, but does not really want to go anywhere. So the owner revs up the boat's engine, makes a lot of noise, and runs the boat in circles around the buoy with the cable supplying all the necessary centripetal force. When the tension of the cable is steady at 12300 N, with what force is the boat's engine pushing the boat? Different physics textbooks treat drag force somewhat differently and use different formulas. For the present purpose, take the water's drag force on the boat to be (450 kg/m) × v², where v denotes the boat's speed. Ignore any drag force on the cable. force: N & TOOLS x10
