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

When gravitational acceleration is needed, use 9.81
m/s2 or 32.2 ft/s2 whichever is applicable.

A box is released from rest at the position shown. Determine its speed (m/s) after traveling 0.8m along the 39.4° inclined surface
if the coefficient of kinetic friction between the box and the surface is 0.2. Round off only on the final answer expressed in 3

Determine the speed of block in Q1 when it moves 2m up the slope using the Work and Energy method and calculate the power of the force P. (If you can apply the principle of work and energy or conservation of enegry.) Plus can you not use the required method for this question. Question 1: A 5kg block is pushed up along the slope as shown. The coefficient of kinetic friction is uk =0.2. Determine the speed of the block when it moves 2 m up the slope using Newton's Second Law. I also gave the answer for Q1 if it helps: V = 2.21m/s
The 65-kg crate is stationary when the force P is applied. Determine the resulting acceleration of the crate if (a) P = 0, (b) P = 223 N, and (c) P = 488 N. The acceleration is positive if up the slope, negative if down the slope. P Part 1 P 65 kg. Incorrect Part (o). We need to decide if the block moves. The easy way to make this decision is to assume that the block does not move and then to test this assumption. If P = 0, what friction force F is needed to keep the block from moving? 4₂ mg Answer: F = 1 260 [#₂ = 0.27 HA=0.20 N N

2. A block travels past point A with a speed of 8 m/s along a smooth surface until it reaches a rough surface of length L=20 m and a coefficient of kinetic friction of 0.8. If the height h₁ = 8 m, and h₂ = 3 m. Determine (A) the speed of the block at point B (B) whether the speed at point C (C) reaches point D. If so, what is the speed at point D, if not, how far is the rough surface that cross the beam?
As indicated in the illustration, two blocks are connected by an inextensible cable. Block A weighs 178.6 kg, while B weighs 252 kg. If the system is released from rest, calculate the acceleration (in m/s2) of block B. For simplicity, let us suppose that the coefficient of friction between block A and the plane is μk = 0.24 and that the pulley is both weightless and frictionless. Make use of the formula g = 9.81 m/s2.
A 1.58 kg block B is moving with a speed of 2.04 m/s as it strikes the 0.54 kg sphere A which was at rest.
