Work on Sliding Object#

Part 1#

The work required to accelerate an object on a frictionless surface from a speed of 2\(v\) to a speed of 3\(v\) is:

Answer Section#

  • 6 times the work required to accelerate the object from \(v\) = 0 to \(v\)

  • 4 times the work required to accelerate the object from \(v\) = 0 to \(v\)

  • 5 times the work required to accelerate the object from \(v\) = 0 to \(v\)

  • Equal to the work required to accelerate the object from 3\(v\) to 4\(v\)

  • Not known without knowledge of the acceleration
