A rock is thrown straight downward with an initial speed of 3m/s into a well. As the same time, the bucket 110 meters down at the bottom of the well is raised at a speed of 2m/s. Determine how far the rock has fallen when it hits the bucket. (Use g = 10 m/s^2).© BrainMass Inc. brainmass.com March 4, 2021, 6:09 pm ad1c9bdddf
From the question, we can know that:
The initial speed of the rock is: v_0 = 3m/s
Then speed ...
The kinematics of a rock being thrown downwards are determined. The solution includes calculations and answer.
