While shopping in a mall, Abdullah helped his mother by pushing a trolley of mass 32kg at a constant speed, for 12m by applying a constant horizontal force of magnitude Fo on the trolley. If he did 420 J of work for this, determine the value of Fo ? Now if he applies a force greater than Fo, how you will describe the subsequent motion of the trolley. 300 N Free-body diagrams for a situation is shown. If the body experiences a net 80 N D force of 50 N left, determine the magnitude of the unknown forces D and E? E A Physics 1 student got confused by a seeming contradiction in Newton's laws and asks her teacher the following question: "If, for every force there is an equal and opposite reaction force, then all forces in nature come in equal and opposite pairs and are therefore balanced. Thus, since there can never be such a thing as an unbalanced force, how can any object ever accelerate?" Explain the mistake in this statement.

Problem A new type of force was discovered by physicists with the following expression: where alpha & beta are constants, and x is the position. The expression above was obtained from the interaction of a massless Higgs Boson (a type of particle) and a black hole. Quantum physicists then decides to design and build a machine that is able to move the Higgs Boson from x2 to x1. How much work should the machine do to achieve this feat? (For simplicity, consider that no energy is lost in the process) Solution To determine the work done we apply the following W = dx Evaluating the above, we get W = | | + e + x for the limits from xi to xf substituting x1 and x2 as the limits, the work done is expressed as W = | / | + ( x1 - ) + ( x15 - x25 )
