OH, thank you gneill! Answer is: F=ma 35N=(21kg)a a=1.667 m/s^2 v^2=0 + 2(1.667)(7.9), 0 being the initial velocity v=5.1 m/s

Thank you. I'm not sure how I would use Newton's Second Law, due to the fact that the normal force and mg are perpendicular to the movement and therefore not contributing to the velocity. I'm so frustrated :)

A solid uniform disk of mass 19.0 kg and radius 70.0 cm (.7 m) is at rest FLAT on a frictionless surface. A string is wrapped around the rim of the disk and a constant force of 35.0 N is applied to the string. The string does not slip on the rim. The string is being pulled. When the disk has...
