A mass m = 2kg is placed at the end of a horizontal spring that has a spring constant k = 500N/m and is compressed to a distance of x = 0.1m from its relaxed point. The spring is the released, shooting the mass horizontally along a track. The mass starts up a 30 degree incline with coefficient of friction µk = 0.4. a. What is the initial energy of the mass shot forward by the spring? b. What distance along the incline does the mass travel? c. If the coefficient of static friction is zero, will the mass fall back down the ramp after reaching the top of its motion? Why? d. If the mass does fall back onto the spring after sliding back down the ramp, how much will the spring be compressed?

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
