The block slides down with a net force of 16.02 N, accelerating at 3.205 m/s².

  • Gravity pulls down the slope with 24.52 N (mg·sinθ) while friction resists with 8.49 N (μ·mg·cosθ).
  • The acceleration g·(sinθ − μ·cosθ) does not depend on mass, since both the pull and the friction scale with weight.
  • At 0° the surface carries the full weight and there is no slide; at 90° the slope is vertical and the block is in free fall.

Next stepSwitch to Motion mode to get the slide time and arrival speed, or Push mode for the effort to drive a load up.
