- FTension = 25 ÂN A ball is attached to one end of a string such that the ball travels in a vertical circular path near Earth's surface. The force diagram of the ball at its lowest point in the circular path is shown above. What is the net centripetal force exerted on the ball? FGravity = 10 N Answer is Work:need help solving theses questionsA block weighing 500 tons is to be raised using the 8° wedge shown which has negligible mass relative to that of the block. The coefficient of static friction between all mated surfaces is us=0.27. Calculate the horizontal force P needed to initiate raising of the block. Show the direction of P in FBDs of the block and the wedge
- Calculate the instantaneous acceleration at t = 5 s.A roller coaster car M equals 60 KG is released from rest at a height H equals 75 m above the ground in slides down a frictionless track the car encounters a loop of radius 20 5 AM A) Find the kinetic energy for the car at the top of the loop. B) In your written work, draw a free body diagram for the car when it is at the top of the loop (note that the car travels on the inside of the loop and it’s upside down at the top). Determine the normal force on the car at this point. C) What is the minimum height, h, from which the car can be released and still maintain contact with the track at the top of the loop?AutoSave w- 445 Saved ON Home Insert Draw Design Layout References Mailings Review View Table Design Layout Tell me Share O Comments Calibri (Bo... 12 v A A° Аa v AaBbCcDc AaBbCcDdEe AaBb( AaBbCcDdEe AaBbCcDdEe AaBbCcDdEe > ev Av No Spacing Paste Normal Heading 1 Heading 2 Title Subtitle Styles Pane I U v ab x, A Dictate Sensitivity total elapsed time, t (s) At = tn+1 - tn (s) Ду V av altitude, Ду 3D Уп+1 — Уп (m) - у (т) At (m/s) 6s 38790 7s 38725 1 8s 38649 9s 38563 1 10s 38474 11s 38370 12s 38256 1 13s 38118 1 14s 37989 1 15s 37853 1 16s 37688 1 17s 37517 18s 37352 1 19s 37182 20s 36980 1 21s 36784 22s 36575 1 23s 36349 1 24s 36122 1 25s 35881 1 26s 35651 27s 35293 1 Page 1 of 1 84 words English (United States) Focus 181%
