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

A scientist tried to launch an experimental rocket in vertical direction. The tracking device of the rocket shows the flight height is at 75
ft when its power shut down. The failure of the parachute to deploy makes the rocket fell freely to the ground after 20 seconds.
Determine: (a) the velocity of the rocket when the powered flight shutdown (b) the maximum height reached by the rocket.

The weight of a Falcon rocket is 500,000 kg. It will be landed on earth at a constant speed of 100 m/s. To slow down the rocket, combustion gases will be fired at the bottom and leave the rocket at a constant rate of 150 kg/s at a relative velocity of 5000 m/s in the direction of motion of the spacecraft for a period of 10 s. If the mass change of the Falcon rocket cannot be ignored, determine (a) the deceleration of the rocket during this period, (b) the thrust exerted on the rocket.
Gayle runs at a speed of 4.10 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 46.5 kg, the sled has a mass of 5.25 kg and her brother has a mass of 30.0 kg.

UBC Engin A trebuchet uses a falling counterweight to launch a projectile. It can be thought of as a machine that converts the gravitational potential energy of the counterweight into kinetic and gravitational potential energy of the projectile. The counterweight has a mass of 100kg and drops 3m. The projectile has a mass of 3kg, and starts on the ground. When it leaves the sling, it has a height of 4m speed of 30. m If the average power used in lifting the counterweight is 48W, find the time it takes to lift it from the ground to its full height. tlifting If the projectile goes from rest to its maximum speed in 1.5s. find the average power used in launching the projectile in this time period.

During a race it was observed that the rider shown in Figure below remained in mid air for 0.75 s.

A 16-Mg jet airplane maintains a constant speed of 774 km/h while climbing at an angle a = 18°. The airplane scoops in air at a rate of 300 kg/s and discharges it with a velocity of 665 m/s relative to the airplane. If the pilot changes to a horizontal flight while maintaining the same engine setting, determine (a) the initial acceleration of the plane, (b) the maximum horizontal speed that will be attained. Assume that the drag due to air friction is proportional to the square of the speed.
