Look at the forces acting on the train parallel to the plane, they are theOriginally Posted by Natasha1
total force tending to slow the train (friction and air resistence), and the
component of the weight (gravitational force on train) down (parallel to) the
The component of the weight down the plain is:
This is in balance with the two slowing forces.
Now there is no component of gravity acting in the horizontal direction, butIt then comes to a level stretch, the friction and air resistance remaining the same. Find how far it travels before coming to rest.
the slowing forces are the same as before. So this is a problem of a body
being slowed by a constant force. As we know this force and the trains
mass we can solve this fairly easily.
