a monkey pushes a loaded sled of mass 240 kg over a frictionless surface on a frozen lake. Starting from rest the monkey pushes the sled 2.3 meters and exerts a constant horizontal force of 130 N, calculate the sled's final velocity? The monkey in previous problem wants to reverse the direction of the sled's velocity in 4.5 seconds, calculate the size of the force the monkey must apply to the sled. I answered the first question I'm wondering about...
