Homework Statement
A projectile of mass m is fired from the surface of the Earth of radius R at an angle a from the vertical with initial speed equal to (1/[sqrt 2]) the escape velocity.How high does the projectile rise?What is its range on Earth's surface?Neglect air resistance and Earth's rotation.
Homework Equations
The Attempt at a Solution
I solved the first part easily by using work-energy theorem.The answer is 2R/3.I hope it is correct.
But I am stuck to solve the 2nd part.Will the normal formulas for the projectile problem give the answer?
