A 10.0 kg block resting on a frictionless surface is attached to an ideal spring with spring constant k. A 50.0 N applied force stretches the spring 100.0 cm from its equilibrium position. If the block is then released, what is its speed as it passes back through the equilibrium position

A100 kg running back runs at 5m/s into a stationary linebacker. it takes 0.5 for the running back to be completely stopped

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
