A force of 15 N is applied at an angle of 30 degrees with the horizontal on a 0.75 block at rest on a frictionless surface.
a. What is the magnitude of the resulting acceleration of the block?
b. What is the magnitude of the normal force?

  • Physics - ,

    Is the mass of the block 0.75 kg? Do not omit the dimensions that go with your numbers.

    The force component in the direction of motion is
    Fx = 15 cos30 = 13.0 N

    Since there is no opposing friction,
    a = Fx/M = 0.37 m/s^2
