PhysicsQ&A LibraryState Newton's three laws of motion. a. b. Show that Newton's first law of motion is a special case of the second law. c. Consider a pulley system in Figure 4. M and M2 are connected by a massless inelastic string. M2 however is connected to a solid sphere of mass M, by a thin rigid rod with negligible mass M, is immersed in a tank of water and the buoyance force acting on M, is Fe. Suppose M;>M2. and Ms is sliding down from the top of the incline. Find the time T and velocity V of m; when it reaches the bottom of the incline. The length and the angle of the incline are Land e. You may assume that the frictional force between the immersed sphere and water is negligibly small. The pulley is massless and frictionless.and the incline is friction free. waterQuestion
