3. A car initially travelingV eastward turns north bytraveling in a circularpath at uniform speedas shown in Figure P6.3.The length of the arcABC is 235 m, and theON35.0°car completes the turnin 36.0 s. (a) What is theacceleration when the caris at B located at an angleof 35.0? Express youranswer in terms of theFigure P6.3unit vectors i and j. Determine (b) the car's average speedand (c) its average acceleration during the 36.0-s interval.13. A roller coaster at the Six FlagsGreat America amusement parkin Gurnee, Illinois, incorporatessome clever design technologyand some basic physics. Each ver-tical loop, instead of being cir-cular, is shaped like a teardrop(Fig. P6.13). The cars ride onthe inside of the loop at the top,and the speeds are fast enoughto ensure the cars remain on thetrack. The biggest loop is 40.0 mhigh. Suppose the speed at thetop of the loop is 13.0 m/s andthe corresponding centripetalacceleration of the riders is 2g. (a) What is the radius of thearc of the teardrop at the top? (b) If the total mass of a carplus the riders is M, what force does the rail exert on the carat the top? (c) Suppose the roller coaster had a circular loopof radius 20.0 m. If the cars have the same speed, 13.0 m/sat the top, what is the centripetal acceleration of the ridersat the top? (d) Comment on the normal force at the top inthe situation described in part (c) and on the advantages ofhaving teardrop-shaped loops.Figure P6.1325. A string under atension of 50.0 N isused to whirl a rockin a horizontal circleof radius 2.50 m atRa speed of 20.4 m/sonafrictionlesssurface as shown inFigure P6.25. As thestring is pulled in,the speed of the rockincreases. When thestring on the table is 1.00 m long and the speed of the rockis 51.0 m/s, the string breaks.

Hi, today I had my engineering mechanics 1 test which I completely screwed up. I was quite confident in the uniform circular motion, but I had this problem in my exam which completely confused me. When I read "upward vertical acceleration" my head just start to spin as I couldn't understand what force could cause an upward acceleration. Could you help me with this problem? I bet it is easier than it looks, but still, I am confused about what is asking me and most importantly about the input it is giving me. I don't have my exam paper with me, but on my body diagram, I knew that on the aeroplane were exerted the Force of Contact Fn1 and the Force m1g in the y opposite direction. On the pilot was acting the Force of Contact with the seat of the aeroplane Fn2 and the m2g in the y opposite direction. Here is the problem: During an air show an aircraft comes out of a dive at the bottom of a circular arc at a horizontal speed of 97m/s. In the cockpit the aircraft pilot of mass 58kg…
