g = 9.8 N/kg A 0.75 kg mаss cоmpresses а spring 0.5m frоm its equilibrium pоsition. The spring hаs a spring constant of 285 N/m. The spring is released and the mass is fired up a ramp that has a coefficient of friction of 0.6. If the ramp has an angle of 25 degrees above the horizontal, how fast is the mass moving when it has experienced a change in height (vertical) of 0.75m?
