from a balloon rising vertically upwards at 5m /s a stone is thrown up...
Problem:
A balloon is rising vertically upwards at 5m/s. A stone is thrown up at 10m/s relative to the balloon. Find its velocity with respect to the ground after 2 seconds.
Solution:
Let's consider the upward direction as positive and downward direction as negative.
Velocity of the balloon:
- Velocity of the balloon = 5 m/s (given)
Velocity of the stone:
- Velocity of the stone relative to the balloon = 10 m/s (given)
- Since the stone is thrown upward, its initial velocity is positive.
- The acceleration due to gravity is acting in the downward direction and its value is 9.8 m/s².
- After 2 seconds, the stone reaches its maximum height and starts falling back.
- Therefore, the velocity of the stone after 2 seconds = initial velocity - acceleration due to gravity × time
- Velocity of the stone after 2 seconds = 10 - 9.8 × 2 = -8.6 m/s
- Here, the negative sign indicates that the velocity of the stone is in the downward direction.
Velocity of the stone with respect to the ground:
- Velocity of the stone with respect to the ground = Velocity of the balloon + Velocity of the stone relative to the balloon
- Velocity of the stone with respect to the ground = 5 + (-8.6) = -3.6 m/s
- Here, the negative sign indicates that the velocity of the stone is in the downward direction with respect to the ground.
Answer:
The velocity of the stone with respect to the ground after 2 seconds is -3.6 m/s.
