1. The escape speed V is the minimum speedneeded to project a mass m upward from the surface of another
mass M (such as a planet, asteroid, or star). It is given by
v =â2GM
R

(a)Calculate the escape velocity v from the surface of the Sun.

USE:

M =1.99 Ã 10³⁰ kg ,

G=gravitational constant 6.67 x10^-11 N*m²/kg²

R =6.96 Ã 10⁸m.

If you weigh 650 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our Sun and a diameter of 16.0 km? Take the mass of the sun to be

ms = 1.99×10³⁰ kg, the gravitational constant to be G = 6.67×10⁻¹¹ N⋅m2/kg2, and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2.

The surface of the sun has a temperature of about 5800K andconsists largely of hydrogen atoms.

find the rms speed of a hydrogen atom at this temperature.
the mass of a single hydrogen atom is 1.67*10^-27kg

The escape speed for a particle to leave the gravational influenceof the sun is given by (2GM/R)^1/2, where M is the sun's mass R itsradius, and G the gravational constant. The sun's mass isM=1.99*10^30 kg, its radius R= 6.96*10^8m And G=6.673*10^-11n*m^2/kg^2.

Calculate the escape speed for the sun

a) Theescape velocity of an object is that for which thetotalenergy of an object in a gravitational field iszero. Write anexpression for the escape velocity of an object ofmass m adistance r away from the center of astar/planet of massM. b) The gravity of a black-hole isso strong that, if tooclose, not even light can escape. The pointat which the escapevelocity equals the speed of light is calledthe event horizon. Whatis the radius of the event horizon of a 1.5solar massblack-hole(MSUN=2Ã10³⁰ kg)? c) Expresstheradius of the event horizon of a 2 billion solar massblack-hole(like the one at the center of our galaxy) in terms oftheEarth-Sun distance (rES = 1.5 Ã10¹¹m).
