They're asking me to write an expression for the work performed on the object over the 7m as a function of the angle X.
The Energy Lost is referring to the ENERGY LOST DUE TO FRICTION
Ive calculated that the expression for work performed on an object over a distance as a function of Angle X.
205.8*(sin(X) - 0.2* cos(X) ) J
I now need to calculate, presuming with the above worked out, the energy lost at the following angles:
10 degrees
20 degrees
30 degrees...
The frictional coefficient given is 0.2 I put that into the frictional coefficient equation but is not making sense.
First i was going to find the two components of the Weight and the horizontal force
Then Fs.
Then Fn
But i don't know how to. Please show!
Homework Statement
An object of mass 3kg is sliding down a slope with a friction coefficient of 0.2. The distance over which it slides down before it hits the ground is 7m. Write down an expression for work peformed on the object over the seven metres as a function of the angle X that the...
