The magnitude of the force of friction between the cart and the track is 0.255 NForce is a push or pulls upon an item because of the object's interaction with some other object. pressure is a power that can exchange the motion of an object. A force can reason an object with mass to alternate its speed, i.e., to boost up. pressure also can be described intuitively as a push or a pull. A force has each significance and course, making it a vector amount. From the equation of motion at constant acceleration:-S = ut + 1/2 at² initial velocity U = 0 0.75 m = 0 + 1/2 a (1.755)² a = 0.48979By applying Newton's second law Feet = maF - F k = maF k = F -ma F k = 0.5 N - (0.5 kg)(0.48979 m/s²)F k = 0.255 NThe phrase 'Force' has a unique meaning. At this degree, it is absolutely appropriate to describe a force as a push or a pull. A force is not something that an object consists of or 'has in it. A force is exerted on one object through another. The concept of a force isn't always restricted to living matters or non-living matters.Learn more about force here:-https://brainly.com/question/12970081#SPJ4
