Question: calculate speed of block at final position. GIven: block on slope of 15 degree incline attached to spring; spring applies force down the slope with stiffness of 450 N/m; frictional coefficient= 0.28 kinetic and 0.3 static; constant force of 150N applied up the slope; final position has...

When do one use the principle of conservation of mechanical energy to find the velocity of a mass, and when would you use the sum of forces equals to the mass times acceleration, and there after use a ds=v dv in order to find the velocity. The specific question related to this is a spring fixed...
