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 500-kg spacecraft first is placed into a circular orbit about the earth
at an altitude of 4500 km and then is transferred to a circular orbit
about the moon. Knowing that the mass of the moon is 0.01230 times the
mass of the earth and that the radius of the moon is 1737 km, determine
(a) the gravitational force exerted on the spacecraft as it was orbiting
the earth, (b) the required radius of the orbit of the spacecraft about
the moon if the periodic times (the periodic time of a satellite is the
time it requires to complete one full revolution about the planet) of the
two orbits are to be equal, (c) the acceleration of gravity at the surface
of the moon.

A space shuttle is in a circular orbit at an altitude of 103 mi. Calculate the absolute value of g at this altitude and determine the corresponding weight of a shuttle passenger who weighs 165 lb when standing on the surface of the earth at a latitude of 45°. Are the terms "zero-g" and "weightless," which are sometimes used to describe conditions aboard orbiting spacecraft, correct in the absolute sense? Answers: ft/sec² Sh lb Wh= i
A spring is used to stop a 50-kg package which is moving down a 20° incline. The spring has a constant k =34 kN/m and is held by cables so that it is initially compressed 50 mm. Knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest. Assume that the kinetic coefficient of friction between the package and the incline is 0.2. 2 m/s 50 kg 8m Cable 20° The maximum additional deformation of the spring in bringing the package to rest is 0.574 x m.

An object of mass m1 slides on a sloped block of mass M2, which in turn slides on a horizontal surface. The slope angle is a constant 3, and both masses are initially at rest. There is no friction between any of the objects, and the masses are subject to the force of gravity -mgêy. Use as co- ordinates the horizontal position x2 of mass m2, and the height y1 of mass m1, as shown in the y4 Y1 M2 x2 diagram to the right. Find the equation of motion of block 2, ä2(t). The expression should only include expressions involving constants: M2, m1, g, and B.
