QUESTION 1     A hot-air balloon is tied to the ground by two ropes.   The diagram shows the forces acting on the balloon. The tension T in each rope is 200 N.     Right click on the button to open the diagram of the hot-air balloon in a new window.       The ropes are untied and the balloon starts to move upwards.         1.1 State the value of the force acting downwards on the balloon immediately after the ropes are untied and before the balloon starts moving. (1)       1.2 State the relationship between unbalanced force, mass and acceleration. (1)       1.3 The balloon has a total mass of 910 kg. The initial unbalanced force on the balloon is 400 N upwards. Calculate the initial acceleration. (2)       1.4 Explain how the upward acceleration of the balloon changes during the first few seconds of its flight. (3)       1.5 While the balloon is still accelerating, the pilot controls the balloon by pouring some sand from the bags. Explain how this affects the upward acceleration of the balloon. (2)
