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

1. A block with a mass of 1kg is initially at rest while held in contact with a compressed spring.
The spring has a stiffness constant of 1000 N/m and is initially compressed by a length of 0.3
meters. Once the mass leaves the spring it will slide 1 meter across the surface of a table where
u, = 0.2 is the coefficient of kinetic friction. There are no frictional losses while the mass is in
contact with the spring, and there are no losses due to air resistance. Only losses are due to the
interaction with the table during the 1-meter slide. The surface of the table is 2 meters above the
floor.
What is the speed of the mass just before it hits the floor?
mass leaves spring
1 meter

A crate of 69 kg simply stands on the moving cart with constant acceleration a. The height from the center of gravity to the cart, L, is 1.4 m, and the angle = 13°. What is the maximum acceleration a (in m/s²) the cart can have without sliding on the cart? The coefficient of static friction between the crate and the cart is μl g = 0.51.

A 100-kg box is towed to move horizontally from rest by a constant force P=200 N. The kinetic friction is μk =0.1. The angle of the force P is θ=30° with respect to the horizontal direction.

Students are given two spherical balls made of different materials, but of identical mass and diameter to experiment with. Each ball is dropped from an initial height, h0. The “sad ball” comes to rest without visibly bouncing when it strikes the tabletop. The “happy ball” bounces up to a final height h, where h< h0 A fellow student wants to use one of the balls in a carnival game where cups are knocked over by a thrown ball. Which ball should they use, happy or sad? Why?
The vehicle shown starts from rest at the bottom of the hill and accelerates up the hill due to the force FR from the road. Note that this is a static friction force and is not dissipative. Vrop = 9.7 m/s m = 1600 kg h = 50 m FR = 7300 N 0 = 25° A) If the vehicle reaches the top of the hill with the speed shown, how much thermal energy is dissipated in the process? B) Assuming that air drag, Fang , is the only dissipative force during this process, try to estimate the cross-sectional area of the vehicle "seen" by the air. In the formula for air drag, regard the car's speed as being a constant v = 5.0 m/s (this speed is roughly half of the starting and ending speeds). Use C = 0.5 for the drag coefficient and p = 1.25 kg/m³ for air density.
