(2) Figure 4 shows the top view of a force table, which will be used to study two-dimensional force equilibrium in this experiment. The numbers denote angles measured counterclockwise from the x-axis. In a trial, two forces, $\vec{F_R}$ with 3.85 N in magnitude and 25° in angle and $\vec{F_G}$ with 9.33 N in magnitude and 100° in angle, are applied on the center of force table, as shown. Another force $\vec{F_B}$ is found to be the equilibrant force of $\vec{F_R}$ and $\vec{F_G}$. i. Write down $\vec{F_R}$ in terms of $\hat{i}$ and $\hat{j}$ (the unit vectors in the x and y directions, respectively). ii. Write down $\vec{F_G}$ in terms of $\hat{i}$ and $\hat{j}$. iii. What is the relation between $\vec{F_R}$, $\vec{F_G}$ and $\vec{F_B}$? iv. What should $\vec{F_B}$ be in terms of $\hat{i}$ and $\hat{j}$? v. What should $\vec{F_B}$ be in terms of magnitude and angle? (2) (Express answers to 3 sig. figs.) i. $\vec{F_R}$ = ________ $\hat{i}$ + ________ $\hat{j}$ (N). [2] ii. $\vec{F_G}$ = ________ $\hat{i}$ + ________ $\hat{j}$ (N). [2] iii. The relation between $\vec{F_R}$, $\vec{F_G}$ and $\vec{F_B}$ is ______________________________________. [2] iv. $\vec{F_B}$ = ________ $\hat{i}$ + ________ $\hat{j}$ (N). [2] v. $\vec{F_B}$ is ________ N in magnitude and ________ ° in angle. [2]

The formula $D = 10e^{-0.4h}$ can be used to find the number of milligrams D of a certain drug that is in a patient's bloodstream h hours after the drug was administered. When the number of milligrams reaches 2, the drug is to be administered again. What is the time between injections? The time between injections is $oxed{}$ hour(s) (Round to two decimal places as needed)
