A particle starts from rest and accelerates uniformly in a straight line. The particle travels a distance of 6.70 m in 2.50 s . How fast, in miles/hour (mph), will the particle be traveling after a time of 4.50 s has elapsed? Assume 1 mile=1609.34 m. Express your answer using three significant figures.
Part B The uncertainty ?p sets a lower bound on the average momentum of a particle in the nucleus. If a particle's average momentum were to fall below that point, then the uncertainty principle would be violated. Since the uncertainty principle is a fundamental law of physics, this cannot happen. Using ?p=2.1×10?20 kilogram-meters per second as the minimum momentum of a particle in the nucleus, find the minimum kinetic energy Kmin of the particle. Use m=1.7×10?27 kilograms as the mass...
