(Hint:since the distance traveled is of interest rather than the time,xis the desired independent variable and nott. Use the Chain Rule to change the variable:dvdt=dvdxdxdt=vdvdx.)dvdt=dvdxdxdt=vdvdx.). Race car drivers routinely cut corners, as shown below (Path 2). Because there is no friction over this portion of the track, the only energy conversion that takes place is between kinetic energy and gravitational potential energy. A crate of mass 100.0 kg rests on a rough surface inclined at an angle of37.037.0with the horizontal. Some books teach you to always think about this term, others only add it if it isnt zero.
