1. At the beginning of a race a runner is speeding up from rest. During this time and assuming the runner's feet do not slip with respect to the track, is the friction from the track on the runner, static or kinetic, and does it point in the direction of the velocity of the runner or opposite to the direction of the velocity of the runner?
