6 VOLT 44 N ZUW A student is testing a silver rock sample with the lab equipment shown in the diagram above. The silver rock completes the circuit and lights the bulb. The student concludes the sample could be which of the following? I. metal II. metalloid III. nonmetal FI GI, II HI, II, III | , II, III​

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
