In the amusement park ride known as Magic Mountain Superman,powerful magnets accelerate a car and its riders from rest to31 m/s (around 70mi/h) in a time of 6.4 s. The mass of thecar and riders is 4100 kg. Find the average net force exerted on the car and riders by the magnets.1____________ NA bowling ball (mass = 7.2 kg, radius = 0.12 m) and a billiard ball (mass = 0.31 kg, radius = 0.028 m) may each be treated asuniform spheres. What is the magnitude of the maximum gravitationalforce that each can exert on the other?1____________ N
When a parachute opens, the air exerts a large drag force on it.This upward force is initially greater than the weight of the skydiver and, thus, slows him down. Suppose the weight of the skydiver is 902 N and the drag force has amagnitude of 1030 N. The mass of the skydiver is 92.0 kg. What are the magnitudeand direction of his acceleration?magnitude 1__________ m/s2
A sphere of radius R is uniformly charged to a total charge of Q. It is made to spin about an axis that passes through its center with an angular speed ω. Find the magnitude of the resulting magnetic field at the center of the sphere.
