A 25.0 kg unloaded sleigh is initially at rest on a horizontal frictionless ice surface. The initial position is the origin (x = 0). A worker applies a force parallel to the x-axis of 80.0 N at t = 0 on the sleigh. The force is withdrawn at t = 2.50 s. Determine the speed and position of the sleigh at t = 2.50 s.
