Homework Statement
The total weight o a gas filled balloon is 1500N.THE BALLOON RAISES AT CONSTANT SPEED OF 10m/s.Calculate the resultant force acting on the balloon?
If the speed is constant, what does that mean about the acceleration? What does Newton's 2nd Law therefore say about the net force on the object?Homework Statement

Homework Equations
The Attempt at a Solution
Yeah that's right. The net force has to be 0. So something has to provide lift to counteract the weight of the balloon. In this case it's the buoyant force that does so (i.e. the balloon floats).as given that the speed is constant ,so there is no acceleration in the ballon.and according to newton 2nd law,force acting on the object is directly proportional to mass of the objectand accelaration,now if we consider this, the net force will be equal to zero.
but i am still confused,am i right?
