1. A 185 g cart is given a quick push up a frictionless incline, giving it an initial velocity of 1.45 m/s. The incline is at an angle of 10.0 to the horizontal. You must show your work to get full credit for this problem. a) What is the cart's initial kinetic energy, i.e. when it leaves the launcher? KE =mv eay @ztty =C85k9)(145s) = .1343 b) What is the cart's change in kinetic energy (Kr-Ko) from the launch point...

5. A cart attached to a spring vibrates with amplitude A. a) What fraction of the total energy of the cart-spring system is elastic potential energy and what fraction is kinetic energy when the cart is at position x= A/2? b) At what position is the cart when its kinetic energy equals its elastic potential energy?

Conservation of energy In the examples you have examined in this lab, as the coaster travels down the track its gravitational potential energy decreases, and its kinetic energy increases. At any point along the path of the coaster, the potential energy plus the kinetic energy add up to the same value. In the absence of friction and air resistance, we find that the total energy (kinetic plus potential) stays the same. For this reason, physicists call the total energy a...

You push a 2 kg shopping mall cart down an aisle (how the heck is “aisle” pronounced “aiyo”). The cart is initially travelling at 5 m/s the moment it left your hand. A) What is the initial kinetic energy of the cart? The cart slowed to a complete stop due to friction. B) What is the final kinetic energy of the cart when it stopped? C) Then, use the work-energy theorem to find the work done by friction. D) If...

A mass attached to a spring is suspended as shown. When the mass is at rest the spring is 12 centimeters long. The unstretched length of the spring is 8 centimeters. The mass is pulled down so that the spring length is 16 centimeters and then released. A graph of the spring length as a function of time is shown. Eight points are labeled A - H in the graph. At which point or points is the spring potential energy...
