Homework Statement
The Radius of Mars is R_m
its mass is m
The radius of Mars (from the center to just above the atmosphere) is R_m and its mass is m. An object is launched from just above the atmosphere of mars.
A) what is the object's initial velocity if its final velocity is V_f
Homework Equations
a=(v^2)/R <--wat v is this?
W=deltaKE
The Attempt at a Solution
i don't know how to start
im thinking i need to calculate the gravity from mars?
but if all I am given is mass and radius
how do i calculate it?
i need to find the amount of work done by Mars right?
