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.

The lower block of mass m2 = 3.2 kg is pulled on by a rope with a tension force of 28 N. The upper block has mass m1 = 1.8 kg. The coefficient of kinetic friction between the lower block and the surface is 0.32. The coefficient of kinetic friction between the lower block and the upper block is also 0.32. What is the acceleration of the 3.2 kg block?
Starting from rest, it takes 1 second for m1 to fall 1.5m. A ring of unknown mass sits on top of m1 as it falls. If m1=2kg and m2=2.5kg, and the incline is frictionless, what force does m1 put on the ring?
The 18 000-kg F-35B uses thrust vectoring to allow it to take off vertically. In one maneuver, the pilot reaches the top of her static hover at 200 m. The combined thrust and lift force on the airplane applied at the end of the static hover can be expressed as F = (44t + 2500t2)i + (250t2 + t + 176 580)j, where F and t are expressed in newtons and seconds, respectively. Determine how long it will take the airplane to reach a cruising speed of 1000 km/hr (cruising speed is defined to be in the x-direction only).
The 55 -lb crate is given a speed of 12ft/s in t=4 s starting from rest. The acceleration is constant. The motor has an efficiency ε=0.65 . Neglect the mass of the pulley and cable.

The 54-lb block rests on the rough surface for which the coefficient of kinetic friction is μk = 0.2. A force F=(40+s2)lb, where s is in ft, acts on the block in the direction shown. The spring is originally unstretched (s= 0) and the block is at rest. (Figure 1) Figure 1 of 1A picture shows a block laying on a horizontal surface with a spring of stiffness k equal to 20 pounds per foot attached to its right side. The other end of the spring is pressed against the wall. Force F is pushing the block to the right and downwards, at an angle of 30 degrees below the horizontal. Determine the power developed by the force the instant the block has moved s = 1.5 ft.
