I realize you can use F=ma but that just confuses me more. a force acts on a block weighing 45 N. The block is initially at rest on a plane inclined at angle theta 15° to the horizontal.The positive direction of the x axis is up the plane.The coefficients of friction between block and plane are mew s = 0.50 and mew k 0.34. A block of mass m = 0.250 kg is pressed against a spring resting on the bottom of a plane inclined an angle θ = 45.0° to the horizontal. The spring, which has a force constant of 955 N/m, is compressed a distance of 8.00 cm, and the block is released from rest. The figure shows a block S (the sliding block) with mass M = 3.3 kg.

Determine the Concept The forces acting on the block are the normal force Fn G Newton's second law of motion states that if a net force acts on an object, it will cause an acceleration of that object. The law addresses the cause and effect relationship between force and motion commonly stated as F = m a, where m is the proportionality constant (mass). Force is measured in SI units of newtons, abbreviated N.
