Planet Gizmo

On Planet Gizmo a small block was observed, State (1), sliding down an inclined plane. A "down-the-plane" coordinate, "s", was imagined with the block at its origin, s = 0 at the time, t = 0+. The mass of the block is: m = 8kg. Initially the elevation of the block and its its kinetic energy were: zB,1 = 6m and KEB,1 = 4J, respectively.

A datum for vector space and potential energy (x = 0, z = 0) and a unit vector basis (I and K) are defined on the sketch.

Planet Gizmo

Consider a block of mass 6 kilograms. The block was first observed moving down a frictionless plane with a kinetic energy of 19,200 Joules, State (1). We set the time (the moment of first observation) to be, t = 0+. The coordinate "S," is added to denote distance down the plane.

Calculate the speed, velocity, kinetic energy, position as a function of time, potential energy, and position and velocity in 3 seconds (not necessarily in order):
