A hot-air balloon is rising upwards at a constant velocity of 5m.s . When the balloon is 100m above the ground , a sandbag is dropped from it. Will the velocity of the hot-air balloon increase , decrease or remain the same immediately after the sandbag has been released ? Explain fully for 5 marks.

• Physics -

The velocity will immediately begin to accelerate upward, but it will begin at its original value (5 m/s)

• Physics -

5 m/s
