SEE ATTACHMENT #1 for a diagram showing parameters.
A rock starts from rest then slides distance L= 5 m down a concave hill to a point which is h= 3 m below starting point.
During the slide, Q= 111 joules of heat are generated, and the final speed is V= 4.8 m/sec.
PART a. Find the average friction force.
PART b. Find the mass of the rock.© BrainMass Inc. brainmass.com June 7, 2023, 2:21 pm ad1c9bdddf
The first step in a solution is to make or observe a careful diagram of the event.
From ATTACHMENT #1, come the following observations:
A. The friction force depends on the angle of the slope, therefore ...
In a step by step solution, the problem is explained and solved.
