A small sphere is at rest at the top of a frictionless semicylindrical surface. The sphere is given a slight nudge to the right so that it slides along the surface. Let R = 1.45 ft and let the angle at which the sphere separates from the cylinder be θs = 34°. The sphere was placed in motion at the very top of the cylinder. Determine the sphare;s initial speed.

Brian is speaking to you and a group of friends. he explains that nuclear power plants are essentially nuclear bombs waiting to explode. this is very worrisome to your friends. which statement is best suited to discredit brian and put your friends at ease? select all that apply. -nuclear power plants and nuclear bombs both use nuclear fission to generate energy, but a nuclear power plant very precisely controls the intensity of the reaction while a nuclear bomb releases the energy in one big explosion. -nuclear power plants use nuclear fusion to generate energy, but a nuclear bomb relies on nuclear fission. since, their reactants differ, their reactions differ. -nuclear power plants have never exploded in their 60 year history. -you agree with brian's statement.
