Circular Motion Problems ANSWERS
Ftension Fgravity= N Circular Motion Problems ANSWERS 1. An g cork is swung in a horizontal circle with a radius of 35 cm. It makes 30 revolutions in 12 seconds. What is the tension in the string? (Assume the string is nearly horizontal) T=time/revolutions= s Period is the time per revolution F=ma Write down N2L Ftension = mv2/r Tension provides net force, acceleration is centripetal Ftension=m(4 2r/T2) Speed equals circumference divided by period Ftension= N Substitute values and calculate 2. A 15 g stopper is swung in a horizontal circle with a radius of meters.
Dec 11, 2012 · How fast can a car travel around an unbanked curve with a radius of 60 meters if the coefficient of friction is 0.40? Using the result from above v=sqrt(0.4 x 10 x 60)=15.5 m/s (higher friction but smaller radius happens to result in the same maximum speed) 6. What is the minimum coefficient friction necessary to keep a car from sliding if it ...
