constant is equal to the magnitude of the force of friction/ normal force. The velocity vs time graph would look like a constant positive horizontal line. The angle of dynamic equlibrium will be less than the angle of maximum static friction3. Friction is not used in the calculations for acceleration since, we assumed that the cart was sliding down the incline with cinstant velocity, and zero acceleration with no net force. The kinetic frictional force is equivalent to the x component of the weight. The acceleration of the object is friction is included would be equal to a = (Fapp - µsl × mg) ÷ m. The experiment could be altered by determining the friction of the cart on a horizontal surface, thus making the velocity constant. By reading off a force sensor, Fkx= Fx. 4. The acceleration equation a=gsi,yields a neglibile value since the value is so small. Due to this value the equation a =g) can be (?used instead. Using an approximation of co=1, Since there was s?zero acceleration, a= g(0) =0.
