Question
Chapter 6, Problem 74GP
To determine
The height achieved by the rock.
Expert Solution & Answer
Answer to Problem 74GP
Solution: 4.41 m.
Explanation of Solution
This question is based on the concept of potential energy.
Given The mass of the rock is m=1.85 kg
The work done on the rock is W=80.0 kg
Formula used
The potential energy of the rock is W=mgh , g is the acceleration due to gravity.
Calculations
Substitute the values of W , m and g in
W=mgh
80.0=1.85×9.8×hh=80.01.85×9.8 mh=4.41 m
Conclusion:
The height attained by the rock can be calculated from the potential energy consideration.
