(a) Find the escape speed of a projectile from the surface of the Moon. (See the front of the test for some numbers you may need here.) (b) Imagine you want to launch a package of mass 3kg from the surface of the Moon in such a way that it will never come back, and when it is very far from the Moon it will still be traveling with a speed of 50 m/s. You have a large and powerful spring whose stiffness is 6 x 10° N/m. How much do you have to compress the spring?
