Problem 129IP

Referring to Example 2–12 Suppose the balloon is descending with a constant speed of 4.2 m/s when the bag of sand comes loose at a height of 35 m. (a) How long is the bag in the air? (b) What is the speed of the bag when it is 15 m above the ground?

Step-by-Step Solution:

Solution 129IP

Part (a)

Step 1 of 6:

Consider a bag of sand comes to loose from a balloon which descends with a constant speed. The height of the balloon above the ground is given. We are going to find the time taken by the bag to reach the ground.

The initial speed of the bag v0 = 4.2 m/s

The acceleration due to gravity g = 9.81 m/s2

The initial above the ground Δx = 35 m
