A small glider is placed against a compressed spring at the bottom of an air track that slopes upward at an angle of 46.0 ∘ above the horizontal. The glider has mass 9.00×10−2 kg . The spring has 670 N/m and negligible mass. When the spring is released, the glider travels a maximum distance of 1.80 m along the air track before sliding back down. Before reaching this maximum distance, the glider loses contact with the spring. the distance of...

A small glider is placed against a compressed spring at the bottom of an air track that slopes upward at an angle of 31.0 ∘ above the horizontal. The glider has mass 7.00×10−2 kg . The spring has 590 N/m and negligible mass. When the spring is released, the glider travels a maximum distance of 1.80 m along the air track before sliding back down. Before reaching this maximum distance, the glider loses contact with the spring. a) What distance...

6. An air-track glider is connected to an ideal spring and can oscillate back and forth on the frictionless surface of the track. The potential energy function of the spring/glider system is U(x) 2.024.0 1.0 in Joules. Here represents the position of the center of the glider in meters. The graph of this function is provided. The y-axis is in Joules and the x- axis is in meters. a. What is the a-coordinate of the center of the glider when...

Problem 2 (40%). While driving, some of a car's kinetic energy is lost to air drag. We would like to estimate the importance of air drag using dimensional analysis and the Buck- ingham a theorem. The relevant parameters are the drag force (FD), the frontal surface area (A) and velocity of the car (v), as well as the density of air (Pair = 1 kg/m3). Answer the following questions: 1. Derive the expression of the drag force as a function...

OAL Combine the concepts of conservation of energy and conservation of momentum in inelastic collisions. In figure a, a bullet and a wooden block are shown in two configurations. In the first configuration, the block, labeled m2, hangs vertically from a ceiling. A bullet, labeled m1, approaches the block horizontally from the left. A rightward arrow points from the bullet and is labeled vector v1i. A rightward arrow, shorter than the first, points from the block and is labeled vector...
