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

If the man pulls the strap with constant acceleration during a short time interval Δt, calculate the force (in Newtons) that he must exert in spinning up the disc. These are the numbers.

Strap's final speed = v = 1.5 m/s.

The small disc's radius is 2 cm
The disc's mass is M = 2.4 kg
The short time interval is Δt = 0.3 s
The disc initially is non-rotating.

A particular bicycle has wheels that are 66 cm in diameter. The radius of the crank armis 18 cm. At its lowest point, the pedal is 16 cm above the ground. A person is pedalingthe bicycle such that the crank arm rotates once every second.Questions:1. Write an equation that models the vertical position of the foot with respect to theground, starting from the lowest point, as the crank arm turns.2. What is the rate of change of the vertical position of the foot when it is at themidline? Explain your answer3. How fast, in kilometres per hour, is the bicycle moving?4. Determine an equation that would model the foot’s position when the cyclist istraveling 5 km/h. Compare this equation to your equation from question 1 andexplain any differences.5. Use calculus to explain why the rotation velocity of a point on the perimeter of awheel is the same as the velocity of the pedal. Use examples to support youranswer.

Hello. Answer is s=5.76m (how far the car travels when the driver slams brake on an inclined surface). I am uploading this question as the example answer's working out was so horrific I cannot follow through. I would like to see working out how the calculations equate to the answer being s=5.76m. Many thanks
When a 5000 lb car driven at 60 mph on a level road is suddenly put into neutral gear (i.e. allowed to coast), the velocity decreases in the following manner: 60 V = mph , 1+() where t is the time in sec. Find the horsepower required to drive this car at 30 mph on the same road. Useful constants: 9 = 22 mph/sec, 1 H.P. = 550 ft.lb/sec, 60 mph = 88 ft/sec.
R ft Rft P lb The block of weight 131 lb is pushed with a force of P = 46 lb on top of two cylindrical rollers with a weight of 32 lb and a radius of R = 1.91 ft. Determine the block's speed after it has been moved 1.48 ft to the left. The block is originally at rest. No slipping occurs. Calculate your answer to two decimal places. Report your answer in ft/s.
A shaft 5.0 cm in diameter and rotating at 2,400 rpm, comes to a full stop in 6.0 seconds. It slows down to 1200 rpm during the first 2.0 seconds and comes to a full stop at the end of the sixth second. The acceleration is constant during both segments of the motion. Determine: a.The total number of turns it completes during the 6.0 seconds it is slowing down, b.the distance traveled by a point on the rim of the shaft during this time, and c.the average acceleration during the first 2.0 seconds in rad/s2.
QUESTION 11 A small box of mass m is placed on top of a larger box of mass 2m as shown in Figure. When a force is applied to the large box, both boxes accelerate to the right with the same acceleration. If the coefficient of friction (static/kinetic) between all surfaces is u, what would be the magnitude of the force and what would be the acceleration ? m F 2m O 1.3m( µ+ g), g O 2.3µmg, µg O 3. 6umg, µg O 4. The information given in the problem is insufficient.

Mechanical Engineering A turbine is running at rated power of 5 MW with the low speed shaft spinning at 12 RPM, with a wind speed of 10 m/s. The drive train has a polar moment of intertia of 50 million kg-m2. The wind suddenly increases in speed to 12 m/s for a 10 second period. What will be the speed of the rotor after that 10 second period, if no control changes are made to the turbine (i.e power delivered to the grid continues at 5MW, and no change in blade pitch angle, no change in Cp, etc.).
