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.

If his constant velocity and the coefficient of kinetic friction between the ski and the snow is 9m/sand 0.80, respectively, compute his velocity when he has skid 20m from his initialposition and a drag force experienced by the skier equivalent to a magnitude of 0.6V^2.
A 10 kg block A rests on a smooth surface and the spring is compressed 0.1 m. It is attached to an inextensible cord over frictionless, weightless pulleys with a mass B of 24 kg, as shown. If the system is released from rest and B travels 0.1 m, what is A's speed? Consider K = 490N/m (spring) and VA = 2 x VB .

Block A with a weight of 100N (mA=10kg) moves to the right (vA=1 m/s) at the moment shown in the figure. Since the kinetic friction coefficient between the surface and block A is μk=0.2, find the speed of block B when it moves 2 meters its weight is 200N (mB=20kg)
The super-container vessel has a total mass displacement of 23000 long tons. This vessel towed by a tugboat with α=20⁰ angle with horizontal. If a constant tension is applied as F=320 kN by the tugboat, please calculate the time to bring the vessel to a speed of 2 knot from the rest. At these low speeds, please neglect the hull resistance that created by the motion. Note: (1 long tons = 1016.05 kg, 1 knot=1.151 mi/hr= 0.5144 m/s)
A small projectile is fired vertically downward into a fluid medium with an initial velocity of 65 m/s. Due to drag resistance of the fluid, the projectile experiences a deceleration of a = (- 0.41v3) m/s2, where v is in m/s. Determine the projectile’s velocity and position 4 s after it is fired.
The figure shows a junction of mass m = 10kg sliding on a rod in a vertical plane. Positioned 1 simpai is stationary and horizontal spring and tensioned Fp = 300N. If the spring constant is k = 1kN/m and the average frictional force between the rod and the junction is F = 30N. Calculate the speed at position 2. (Ans: 3.47m/s)
Show the complete solution. Put notes on steps. The wooden block (mass m = 0.6165 kg) is released from rest at A by a compressed spring (compressed length 0.6 m, undeformed length 1 m, spring constant k = 150 N/m). The block is allowed to slide through the rough horizontal surface (A to B), then along the smooth circular ramp (B to C, central angle 0 = 45°, until the block is released after point C. Calculate the speed of the block at points B and C. Also, what is the magnitude of the normal force exerted to the block just before the block leaves the ramp? Neglect the geometry of the block.NOTE: Use Work-Energy Method to solve for the speeds; use Force-Mass-Acceleration (FMA) Method to compute for the normal force.

Q) Write an expression for the rate of energy expenditure whenshe jogs at the same constant speed up a slope of 4.99 degrees. Assume whatever frictional or drag forces are the same in each case. Your answer should be in terms of the symbols given in the problem statement and g(9.80 m/s^2)
