A block slides down a frictionless plane having an inclination of 14.3°.

If the block starts from rest at the top and the length of this incline is 1.77 m, find the acceleration of the block.

  • Physics -

    The component of the weight force in the direction down the ramp is
    F = M g sin 14.3
    Set this equal to M a and solve for the acceleration, a. This works because there is no friction to consider.

    Note that the mass M cancels out.

    The length of the incline is information that is not needed.

    o...the length of the incline is needed for the next question, which i need help with as well

    it asks what is the the velocity at the bottom of the incline?

    how would u figure this out? what formula would u use (if any)?
