A balloon of gross weight W newton descends with an acceleration `fm//s^(2)` The weight that must be thrown out in order to give the balloon an equal upward acceleration will be:

A balloon of mass M descends with an acceleration a_(0) . The mass that must be thrown out in order to give the balloon an equal upwards acceleration will be

A balloon of mass M descends with an acceleration a_(0) . The mass that must be thrown out in order to give the balloon an equal upwards acceleration will be

A hot-air balloon of mass M is descending vertically with downward acceleration of magnitude a. How much mass (ballast) must be thrown out to give the balloon an upward acceleration of magnitude a? Assume that the upward force from the air (the lift) does not change because of the decrease in mass.

A balloon of gross weight w newton is falling vertically downward with a constant acceleration a(lt g) . The magnitude of the air resistance is :
