WebFeb 19, 2004 · So for your linear motion, you start out with an initial velocity v and you have a force = mu * N acting in the direction opposite v. N is your normal force = mass * g. You will need to know your mass and gravity, or perhaps mu is a force in your case. Basically its the same problem as a block stopping due to friction. WebCharacteristics of a constant velocity motion. The constant velocity motion is a motion that has as a trajectory a straight line and a constant velocity.That a body is moving at a constant velocity means that there is no force or acceleration that is forcing him to move, this is why a body in a constant velocity motion the acceleration is null. butcher block countertops paWebAug 24, 2024 · Step 1: Write the general slope-intercept form of a line: y=mx+b.
