Questions 17-20 A small object of mass m is launched from the surface of the Earth with a speed of to in a direction perpendieular to the Earths surface. 17. What is the total mechanical energy of the object at its starting point in terms of m, uo. the radius of the Earth R, the mas of the Earth M, and the gravitational constant G
An object with mass m away from the center of the center of the earth with mass M by the relationship r = h + R where R the radius of the earth and h the object height from the surface of the earth.At any height h, the value of the acceleration earth gravity equal half its value at the surface?
Suppose an object is launched from Earth with 0.52 times the escape speed. How many multiples of Earth's radius (RE 6.37 x 106 m) in radial distance will the object reach before falling back toward Earth? The distances are measured relative to Earth's center, so a ratio of 1.00 would correspond to an object on Earth's surface. For this problem, neglect Earth's rotation and the effect of its atmosphere For reference, Earth's mass is 5.972 x1024 kg. Your answer is...
Derive an expression for the energy needed to launch an object from the surface of Earth to a height h above the surface. Ignoring Earth's rotation, how much energy is needed to get the same object into orbit at height h? Express your answer in terms of some or all of the variables h, mass of the object m, mass of Earth mE, its radius RE, and gravitational constant G.

Suppose an object is launched from Earth with 0.56 times the kinetic energy for escape. How many multiples of Earth's radius (RE = 6.37 x 106 m) in radial distance will the object reach before falling back toward Earth? The distances are measured relative to Earth's center, so a ratio of 1.00 would correspond to an object on Earth's surface.

5. A rocket is launched horizontal from the surface of earth. The launch velocity of the rocket is 0.80 vese where vesc = V2GM/R is the escape velocity from the surface of earth. Determine the maximum distance the rocket will reach above the center of earth. Express your answer as a multiple of earth's radius, R. (Answer 3.6) %3D
2. A rocket of mass m is fired vertically from the Earth, with an initial speed U. It rises to a height R/2 before falling back to Earth, where R is the radius of the Earth. Calculate U in terms of G, M (the Earth's mass) and R. The rocket is fired with the same initial speed, but this time at an angle 45° to the horizontal. Calculate its angular momentum J and total energy E, and use these to...
P3. A rocket of mass -1.20x10'kg is launched vertically upward from point A on the earth's surface with an initial speed v, 7.00km/s a. (12) Calculate the maximum height H of point B above the earth's surface at which the rocket will momentarily come to rest, before it starts falling back to the earth Hint: Use conservation of energy. b. (4) Determine the gravitational acceleration a at point B. c. (9) Calculate the total mechanical energy E of the rocket....
A projectile with mass 201.0 kg is launched straight up from Earth's surface with an initial speed 10.7 km/s. What is the maxium height of the projectile, as measured from the center of the Earth? Answer in units of Re (g= 10 m/s^2, Re= 6.371 x 10^6 m) The answer is 4.9 but how, Please and Thankyou
