Calculate the ratio of H* ions to OH ions at a pH = 7 Find the concentration of H+ ions to OH ions listed in
Table B of your Student Guide. Then divide the H+
concentration by the OH concentration. Record this
calculated ratio in Table A of your Student Guide.
Compare your approximated and calculated ratios of Ht
ions to OH ions at a pH = 7. Are they the same? Why or
why not? Record your comparison in Table A.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
