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** =**â**2GM

R

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

USE:

**M** =1.99 Ã 10^{30} kg ,

**G**=gravitational constant 6.67 x10^{-11} N*m^{2}/kg^{2}

**R** =6.96 Ã 10^{8}m.
