Show your work for all parts using good problem solving practices. Note there are questions or the back of the sheet. Uli Unicorn is riding one of the Bryan elevators. Uli's mass is 70 kg and the elevator's mass is 1930 kg, for a combined total mass of 2000 kg. As it is leaving the fourth floor, the elevator accelerates at 0.2 m/s^2 downward. The elevator is held up by a counterweight, as shown in the picture below. 1. Draw force diagrams and write force equations 7. 70kg for BOTH the counterweight system and for the 2:193029 .O.Qoy ㅓ 15 elevator/Uli system. Make sure to denote direction of acceleration and positive direction for both diagrams CW 5/ TEN Fing TA noforce friction are - these thest - 2 equations? s distingish different masses 2. Determine the mass of the counterweight needed ? to achieve the given acceleration as the elevator leaves fourth Bryan.. (need to work on solving symbolically) counterweight Ft - Fing ma which mass - 3 finish 3 is this for Cover)
3. Draw a force diagram and write a force equation for Uli. con not figure out how to correchy write this force - I no force •FN Japat friction "Fing since a -2 EF=m -FN-Fring=ma {E=0 F-0 this is at off conven 14. Determine Uli's apparent weight as the elevator leaves fourth Bryan. (Without finding the equation this is hard to determine) -4 F is apparent weight, you have equation M
