5. A large rock is launched with a speed of 13000 m/s towards the atmosphere.

a) Is that enough to escape earth’s atmosphere? (Derive the escape speed where G = 6.7 x 10^-11, M = 6.0 x 10^24 kg, and R = 6.4 x 10^6)

b ) Now, find the speed of the rock if it were to be in circular orbit around earth.

c) Find the Buoyancy of a box with a volume V = 10 m^3 that is submerged in a pool of water and held down by a string. The density of the box is 200 kg/m^3. The density of water is 1000 kg/m^3.

d) find the tension of the string that is holding the box down.

A rock is launched off a cliff at a speed of 12.1 m/s at an angle of 35.0 degrees above the horizontal. The height of the cliff is 16.1 m. How far horizontally from the edge of the cliff does the rock land (to one decimal place)? In your solution, also sketch the x-t, y-t, vx-t, vy-t, ax-t, and ay-t diagrams.

P1: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 x 1024 kg. Your...

If a 2500 kg rocket is launched from the Earth's surface at a speed of 5 km/s, how high can it reach before it returns back down?(Mass of Earth is 5.98 x 10^24kg, radius is 6.38 x 10^6m)? Find the gravitational accelerations at this highest point. This would be the initial downward acceleration of the rocket.
