Two people pull a 95.0 kg sled along an slippery surface. One person pulls with a constant force of 114 N [N 20.0° E] with the other pulls with a constant force of 135 N [N 15.0° W]. Both people are pulling with a force parallel to the ground. What is the acceleration of the sled, assuming the surface has a coefficient of kinetic friction of 0.031. Remember to show all steps

Three people are at rest at the same spot on an icy surface and push off of each other. Take this initial position to be the origin. At a certain time later, one person of mass 75 kg is at the point (4.2 m, -8.3 m), and another of mass 80 kg is at the point (5.5 m, 1.4 m). What are the coordinates of the third person with mass 70 kg? (Assume friction can be ignored.)

Now, suppose that Zak's younger cousin, Greta, sees him sliding and takes off her shoes so that she can slide as well (assume her socks have the same coefficient of kinetic friction as Zak's). Instead of getting a running start, she asks Zak to give her a push. So, Zak pushes her with a force of 125 N over a distance of 1.10 m. If her mass is 29.0 kg, what distance d2 does she slide after Zak's push ends? Remember that the frictional force acts on Greta during Zak's push and while she is sliding after the push. Express your answer in meters.
