Several people are riding in a hot-air balloon. The combined mass of the people and balloon is 284 kg. The balloon is motionless in the air, because the downward-acting weight of the people and balloon is balanced by an upward-acting 'buoyant' force. If the buoyant force remains constant, how much mass should be dropped overboard so the balloon acquires an upward acceleration of 0.28 m/s2?

Question

bobpursley · Answer

weight=ma but m is the weight left weight=(284-Weight)*.28m/s^2 solve for weight

Donna · Answer

but if you have two variables how do you solve? I understand that force=ma so the normal force is (284)(9.8)=2783.2, but I don't really understand how to determine when acceleration is .28
