Questions #17-20: A 500.-g mass is attached to the end of an ideal, massless spring with constant 8.50 N/m, as shown. (These values are similar to those used in PHYS 151L Lab spring experiments.) The mass is initially displaced to the right of the spring's equilibrium position by a distance of 6.00 cm, then released at t= 0 and allowed to oscillate freely. For the following questions: • Define the +x-direction for all quantities to be to the right. Each of the following answers may be POSITIVE or NEGATIVE! • Define x = 0 at the spring's equilibrium position. Neglect all friction. . . . 18. What is the x-component of the mass's velocity 7.10 seconds after it is released? Convert your final answer to meters/second: m/s • Calculate and enter your final answer to at least 2 significant figures. There is no penalty for including too many significant figures, but rounding to too few sig figs may cause Laulima to judge your answer to be wrong. • Do NOT enter units with your answer, enter only a numerical response. Laulima will count non-numerical answers as incorrect.

h A steel wire of length L connects a hook on the ceiling to a bowling ball, With the steel wire kept taut, the bowling ball is lifted to a height h above the floor, and then released. The bowling ball swings back and forth in the motion of a pendulum. After the bowling ball is released, what is the maximum height above the floor that it reaches?
