[QUOTE="faulkton, post: 3350535, member: 561910"] 1. What is the acceleration of a 20k/g pail of cement that is pulled upward with a force of 200n? Sprinting near the end of the end of a race a runner with a mass of 60kg accelerates from a speed of 6m/s to 7m/s in 2s. 2. What is the runner's average acceleration during this time? To gain speed the runner produces a backward force on the ground, so that the ground pushes the runner forward providing the force necessary for acceleration. 3. Calculate this average force.
