Report the answers in standard units, converting if necessary, and do not include the unit in the answer field. You may use scientific notation if you prefer, so an answer like Ax = 0.000543 m could be entered as 0.000543 or as 5.43E-4 for full credit. Report more digits than are significant. For the sig figs, enter the integer number only (ie. 1, 2, 3,.). 1) A 15.0 kg ball is suspended from a ceiling in a lecture hall by a cord attached to a spring that is observed to stretch 8.500 cm from its natural length. Calculate the magnitude of the tension in the cord. 2) How many significant figures does the previous answer have? 3) A 15.0 kg ball is suspended from a ceiling in a lecture hall by a cord attached to a spring that is observed to stretch 8.500 cm from its natural length. Calculate the spring's stiffness constant. 4) How many significant figures does the previous answer have? 5) A 15.000 kg ball is suspended from a ceiling in a lecture hall by a cord attached to a spring with stiffness constant 1000. N. Calculate the deformation in the spring. 6) How many significant figures does the previous answer have? 7) A ball is suspended from a ceiling in a lecture hall by a cord attached to a spring with stiffness constant 1000. N that is observed to stretch a distance 2.95 cm from its natural length. Calculate the mass of the ball. 8) How many significant figures does the previous answer have?
