Question

Hello,

During a lab where you race 2 cars downward on a 30* angle slope, we got graphics of the different energies in play. (Gravitational, kinetic and Total in depending on time). Afterwards, we need to answer this question: Calculate non-conservative work exerted by the force of air resistance for both cases (meaning for both cars).

So my question is, are the asking me to calculate

Wnc = deltaE?

thank you

Answer 1

Look at this relationship

GPE lost= KE gained + nonconservativework

so figure the air fricion losses from the changes in energy.

Answer 2

ohhh I see, thank Bob!

Answer 3

*thanks
