Homework Help: Physics

Posted by Lindsay on Wednesday, November 28, 2007 at 3:21pm.

A research balloon of total mass 200 kg is descending vertically with a downward acceleration of 3.2 m/s^2. How much ballast must be thrown from the car to give the balloon an upward acceleration equal to 2.8 m/s^2, presuming that the upward lift of the balloon does not change?

Could someone at least show me the first steps? I don't even know where to begin.
