A hot-air balloon is descending at a rate of 2.0 m/s when a passenger drops a camera. If the camera is 45 m above the ground when it is dropped, (a) how long does it take for the camera to reach the ground, and (b) what is its velocity just before it lands? Let upward be the positive direction for this problem.
Step 1 of 4
A camera is dropped from a hot air balloon which is descending with a speed of , when the balloon is at the height of . Here we need to calculate the time taken by the camera to reach the ground and the final velocity with which the camera lands on ground.
Initial speed of camera,
Acceleration of camera,
- Time taken by camera to land on the ground,
- Final velocity of the camera when it lands on ground,
