									LT2 - Forces on an Inclined Plane Practice Problems


Learning Target
  2) I can utilize the perpendicular and parallel forces to calculate other quantities
     related to its motion (for example: acceleration, velocity, time, distance, etc).


Problems:
  1. A crate weighing 562N is resting on a plane inclined 30.0º from the
     horizontal. What is the magnitude of the acceleration parallel to the
     surface of the plane?

  2. After 4.00s, how fast will the crate be moving (assuming no friction).

  3. Stacie, who has a mass of 45kg, starts down a slide that is inclined at
     an angle of 47º. Assuming that there is no friction, how fast will she
     be traveling after 2.5s?

  4. Jeff, who weighs 640.0N, is getting ready to sled down a snowy hill
     that has an incline of 63º. Assuming no friction, how far has he gone
     after 15 seconds of sledding?

  5. A 635N box starts sliding from rest at the top of a 39º incline.
     Assuming no friction, how far has the box traveled when it has reached
     a velocity of 2.3m/s?
