An airplane moves 100 m/s as it travels around a vertical circular loop which has a 1.0-km radius. What is the magnitude of the resultant force on the 50-kg pilot of this plane at the bottom of this loop? A 4.0-kg block sliding on a horizontal frictionless surface is attached to one end of a horizontal spring (k = 200 N/m) which has its other end fixed. If the block has a speed of 4.0 m/s as it passes through...

A motorbike performs the'' loop the loop' 'stunt where it travels in vertical circular motion. At the top of the circle the centripetal force is fn+mg=mv^2/r. It must have a minimum speed to stay on the track. The book says to minimise velocity the normal force has to equal zero. My question is how can a normal force be zero if something has to be oppose the static frictional force.

A student with mass 58.0 kg rides on a roller coaster with a vertical loop. At the top of the loop the track has a radius of 19.7 m and the roller coaster moves at speed of 21.9 m/s at the top. Determine the normal force from the seat on the student at the top of the loop. Give your answer in newtons (N) and with 3 significant figures.
