Unformatted text preview: and magnitude o² the gravitational ²orce on the mass located at ( x, y ) = ( d, d )? Problem 8 Calculate the numerical value o² the ratio v moon /v esc where v esc is the usual escape velocity, i.e. velocity required to escape to in³nity, whereas v is the minimum speed needed at the sur²ace o² the earth in order to reach the sur²ace o² the moon. ( Keep in mind that once the object is close enough to the moon, the moon’s gravitational pull will take over.) 1...
