Solving a problem in physics section 22 point 89 mechan

Product description

• The pilot on the plane made a "loop the loop" of radius R = 240 m. Determine the effect of pressure on the pilot's seat in the upper and lower points, if its mass m = 75 kg, and the aircraft's speed υ = 210 km / h. What speed υ0 must have a plane with the same radius of the loop, the force of pressure on the pilot's seat at the highest point was equal to zero?
