A speed skater goes around a turn that has a radius of 27 m. The skater has a speed of 15 m/s and experiences a centripetal force of 470 N. What is the mass of the skater?
Homework Answers
centripetal force = mv^2/r
mv^2/r = 470 N
m = 470*r/v^2
m = 470*27/15^2 = 56.4 kg
MAss of skater = 56.4 kg

A car travels at a speed of 21 m/s around a curve of 27 m. m = 1500 kg (i) What is the net centripetal force needed to keep the car from skidding sideways? (ii) Were there no friction between the car’s tires and the road, what centripetal force would be provided just by banking the road at 29o? (iii) Now, suppose a friction force is also present and prevents the car from skidding. Calculate the magnitude of the normal...
