Loop Top

What is the speed of the rider in the top of the loop?

A special electronic sensor is built into the seat of a car carrying to around a circular loop-the-loop in an amusement park. The sensor measures the magnitude of the normal force exerted on the pilot seat. The loop-loop ride in the vertical plane and its radius is 16 m. Sitting in his seat before the trip begins, a pilot is the level and fixed, and the electronic sensor reads 760 N. At the top of the loop, the rider is upside down and around, and the sensor reads 380 N. What is the speed of the rider in the top of the loop?

The centrifugal force top is Fc = m • R / = m • v ² (the one to the positive direction) (You want to memorize a ² = v / R) "ideally" in the top of the loop this force is greater than the downward gravitational force Fg = m •-g. (Set and negative) You say that the net force Fn = Fe + Fe = 380N. It Faith tells him and he knows Fe and has the equation Fc = m • V ² / R. You know the mass because Fg = m • and -9.81 V can be solved To solve problems like this "hunting" by the equations. The equations are in this case .. Fn + Fe = Fc Fc = m • m • a = v ² / R Fr = m • g
