Prelecture Exploration: Energy Conservation in a Block-Spring System Terry and Jolon are enjoying their physics class, and want to learn more about work and energy. They decide to stay after class to discuss the topics and see whether they can gain a better understanding. They use this simulation to help them. The system in this simulation consists of the block and the spring. In the simulation, the friends should assume that the surface is level and frictionless. They can use...

following types of forces?PSS 21.1 Conservation of energy in charge interactions Learning Goal: To practice Problem-Solving Strategy 21.1 Conservation of energy in charge interactions. An alpha particle (a), which is the same as a helium-4 nucleus, is momentarily at rest in a region of space occupied by an electric field. The particle then begins to move. Find the speed of the alpha particle after it has moved through a potential difference of-3.45x10-3V.The...

mum Problem 1 (15 points) In an oscillating spring-mass system, the energy of the system is continually changing from kinetic energy to potential energy and back again. (Ignore the friction force). (5 points) Discuss in detail the energy conservation principle of the spring-mass system using your own words including the possible changes of both kinetic and potential energies during this motion? (5 points) At what point in the oscillation will the potential energy of the spring-mass system be highest? Why?...

Use the work-energy theorem to argue that frictional forces always tend to slow objects down.
PROBLEM 2 (5 points). Momentum and Mechanical Energy conservation A rifle bullet with mass 150 g strikes and embeds itself in a block with mass 1000 g that rests on a frictionless, horizontal surface and is attached to a coil spring. The initial velocity of the bullet was 700 m/s. The impact compresses the springy a distance x. The spring constant is 550 N/m. The spring is ideal. a) Find the magnitude of the block's velocity (with the bullet stuck...
