Question

moore (dam5379)-HW6- Clreul 016 10.0 points A coln is placed 34 cm from the center of a horlzontal turntable, inttially at rest. The turntable then begins to rotate, when the speed of the coin is 130 cm/s (rotating at a constant rate), the coln just begins to slp. The acceleration of gravity is 980 cm/s2 What is the coefficient of static friction be tween the coin and the turntable? 017 10.0 points A fighter plane lying at constant speed 590 m/s and constant altitade 11000 m makes a turn of curvature radius 35000 m plane's turm Answer i ls 018,(part li2) 10:0 points

Explanation / Answer

16)

Here Centripetal force is balanced by frictional force

mV2/r =umg

=>u=V2/rg = 1302/34*980

u=0.5072

17.

Weight of pilot

W=754.6 N

Centripetal force

F=mV2/r =77*5902/35000 =765.82 N

Apparent Weight

Wapparent=sqrt(754.62+765.822) =1075.13 N
