In a skeleton timed race, only a little advantage is gained by getting a running start. (This is because the initial kinetic energy is small compared with the gain in gravitational potential energy on even small hills). To demonstrate this, find the final speed and the time taken for a racer who travels 70 m down a 26 slope under the following conditions? Treat the effect of friction to be negligible. Include units as appropriate below. (a) The racer starts the run at rest. U41= t = In a skeleton timed race, only a little advantage is gained by getting a running start.
