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 the 2nd one.

A 41 kg girl and a 6.5 kg sled are on the frictionless ice of a frozen lake, 18 m apart but connected by a rope of negligible mass. The girl exerts a horizontal 4.5 N force on the rope. What are the acceleration magnitudes of (a) the sled and (b) the girl? (c) How far from the girl's initial position do they meet? I really only need part (c). I have (a) = .6923 N and (b) = .1097...

1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...
