Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

A particle of mass m is travelling on top of a table, in a circle of radius r1, with a speed of v1. Suddenly, the attached cord is pulled
down through a hole in the table, with constant speed v,. Neglect the size of the particle, the mass of the cable, and neglect friction
between the particle and the table.
1) Determine a symbolic solution for the new radius r2 when the speed of the mass v2 is achieved.
2) Determine a symbolic solution for the time required for the particle to reach the speed of v2. Take time zero as the instant at which
pulling on the cord begins.
3) Determine a symbolic solution for the work done on the particle between r1 and r2.
4) Numerically evaluate r2, t, and the work done on the particle for v1 = 1 ft/s, v2 = 2 ft/s, Vr

A crate, initially traveling horizontally with a speed of 18 ft/s, is made to slide down a 14 ft chute inclined at 35◦. The surface of the chute has a coefficient of kinetic frictionμk, and at its lower end, it smoothly lets the crate ontoa horizontal trajectory. The horizontal surface at the end of the chute has a coefficient of kinetic frictionμk2. Model thecrate as a particle, and assume that gravity and the contact forces between the crate and the sliding surface are the onlyrelevant forces.Using conservation law methods, ifμk= 0.35, what is the speed with which the crate reaches thebottom of the chute (immediately before the crate’s trajectory becomes horizontal)?
Two cars A and B, each having a mass of 1.6 Mg, collide on the icy pavement of an intersection. The direction of motion of each car after collision is measured from snow tracks as shown in (Figure 1). Assume 0 = 40°. The driver in car A states that he was going 60 km/h just before collision and that after collision he applied the brakes, so that his car skidded 4 m before stopping. Assume that the coefficient of kinetic friction between the car wheels and the pavement is μ = 0.15. Figure A B B 1 of 1 Part A Determine the approximate speed of car B just before collision. Note: The line of impact has not been defined; furthermore, this information is not needed for solution. Express your answer to three significant figures and include the appropriate units.

You have been chosen as the test subject for the newest attraction at Canada’s Wonderland. This attraction is a single-person roller coaster ride that has a 25.0 m drop followed by a collision with a plunger attached to a large spring that brings the ride to rest. The plunger/spring mechanism is composed of a large spring with a mass of 62.5 kg made of pure iron..The cart has a mass of 75.0 kg and starts at rest from the top of the track. To determine the total mass of the cart during the ride you must add your mass to the system. As the cart moves down the track it has been determined that friction in the wheels and axles results in the production of 12750 J of thermal and sound energy combined. The plunger/piston at the bottom of the device has been designed to stop the cart with a maximum acceleration of 5.00 g’s (i.e. 49.0 m/s2). What is your approximate mass in kilograms? MY MASS IS 82 kg Problem 1: The cart with you inside of it starts from rest at the top of the ride.…
2. Block 1 of mass m, slides from rest along a frictionless ramp from height h = 1.60 m and then collides (completely inelasticly) with stationary block 2 of mass m2 = 3.00 m..
