WebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s. WebWe'll use the Pythagorean theorem to find the magnitude of the total velocity vector. v^2= {v_x^2 +v_y^2} \qquad\text { (The Pythagorean theorem.)} v2 = vx2 + vy2 (The Pythagorean theorem.) v=\sqrt {v_x^2 …

WebFeb 20, 2024 · The SI unit for velocity is meters per second or m/s, but many other units, such as km/h, mi/h (also written as mph), and cm/s, are in common use. Suppose, for example, an airplane passenger took 5 seconds to move −4 m (the negative sign indicates that displacement is toward the back of the plane). His average velocity would be 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.
