How hard are we talking about? ;-)

*) A projectile is projected upwards with a blistering speed of 5km/s. If the earth has a radius of 6400 km, calculate how high about the earth's surface does the projectile reach (neglect the rotation of the earth and consider earth to be a perfect sphere )

2) A man stands at the bottom of an incline (alpha). He throws a projectile with an angle beta with respect to the incline. If you consider the man to be at origin. Find the co ordinates at which the projectile hits the incline|dw:1409406103623:dw|
