Two-Stage Motion
Part of the Mechanics section of Coddy's Physics journey. Lesson 43 of 97.
Many motions come in stages: a push and then a slide. Each stage has its own forces, so its own constant acceleration.
The velocity at the end of stage 1 is the starting velocity of stage 2.
Each stage is a straight line with its own slope; they meet at the hand-over velocity.
Challenge
A sled starts from rest on level snow. A rope pulls it forward, to the right, with for while kinetic friction holds it back with ; then the rope is let go. Taking forward as positive, find the time the sled slides before it stops.
