A block is connected between two springs on a frictionless, horizontally level track. The other end of each spring is respectively anchored to a vertical pin set at opposite ends of the track. If the spring constants are determined to be 3.00 N/m and the period of oscillation for the block when slightly displaced from equilibrium point is 0.600 s, compute what is the mass of the block?
Elm Street has a pronounced dip at the bottom of a steep hill before going back uphill on the other side. Sitting on the scale while the car is parked gives a reading of 588 N. Analyze your data, using a graph, to determine the dip's radius of curv..
