6a. A 158g block is pressed against a spring of force constant 1.47kN/m until the block compresses the spring 12.0cm. The spring rests at the bottom of a ramp inclined at 57.3 to the horizontal. Using energy considerations, determine how far up the incline the block moves before it stops if there is no friction between the block and the ramp. Submit Answer Tries 0/10 6b. How far up the incline does the block move before it stops if the coefficient of kinetic friction is 0.420? Submit Answer Tries 0/10
