In short-track speed skating, the track has straight sections
and semicircles 16 m
in diameter. Assume that a 64kg
skater goes around the turn at a constant 11m/s
.
Part A
What is the horizontal force on the skater?
part B
What is the ratio of this force to the skater's weight?

A race track is being design to allow racing in a circle to travel at 80 m/s (about 179 mi/h). If the radius of the circular track is to be 150 m, at what angle should the race traffic be bake in order to a c travel at 80 m/s around the track without the aid of friction Be sure to draw the relevant force diagram(s) and show all steps (do not just use the magic Banked curve...
Question 6) A 50.0 kg skater arrives at the bottom of a vertical circular track at 32.0 m/s. The radius of the track is 15.0 (m). Friction is negligible. Ignore the size of the skater so the radius of her motion is the hane as the 15.0fm] radius of the track. Point C is at the top of the track. The track goes a little bit farther than point C but we don't need to figure out what happens after...
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?
A speed skater goes around a turn that has a radius of 26 m. The skater has a speed of 16 m/s and experiences a centripetal force of 460 N. What is the mass of the skater?
A speed skater goes around a turn that has a radius of 30 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?
A speed skater goes around a turn that has a radius of 32 m. The skater has a speed of 12 m/s and experiences a centripetal force of 460 N. What is the mass of the skater?
A mini train is moving at a constant speed along a straight, horizontal track. The train consists of an engine, which is in front, and one car that is being towed by the engine by a cable. The engine and car are not touching. There is a coefficient of kinetic friction of between the engine and the track, and between the car and the track. The coefficient is the same for both; it is 0.100. The engine has a mass...
A NASCAR racecar rounds one end of the Martinsville Speedway. This end of the track is a turn with radius approximately 57.0 m. If we approximate the track to be completely flat and the racecar is traveling at a constant 26.5 m / s (about 59 mph) around the turn, what is the racecar\'s centripetal (radial) acceleration? What is the force responsible for the centripetal acceleration in this case? friction, normal, gravity, or weight? To keep from skidding into the...
