A 124 kg balloon carrying a 22kg basket is descending with a constant downward velocity of 20m/s. A 1 kg stone is thrown from the basket with an initial velocity of 15m/s horizontally measured from the person in the basket. The person sees the stone hit the ground 5 seconds after it was thrown. The balloon continues its downward descent with the same constant velocity of 20m/s. Just before the stone hits the ground, what are the horizontal and vertical velocity components measured by an observer i) in the basket ii) on the ground.
2. A 124 kg balloon carrying a 22kg basket is descending with a constant downward velocity of 20m/s. A 1 kg stone is thrown from the basket with an initial velocity of 15m/s horizontally measured from the person in the basket. The person sees the stone hit the ground 5 seconds after it was thrown. The balloon continues its downward descent with the same constant velocity of 20m/s.
Just before the stone hits the ground, what are the horizontal and vertical velocity components measured by an observer
i) in the basket
ii) on the ground.
Using the concept of relative velocity we can find the speed of a stone before hitting the ground with respect to the person standing at rest on the ground as well as with respect to a person moving in a balloon .
