A DVD with an initial angular speed of $4\mathrm{.}0$ rad$/$s has an angular acceleration $1\mathrm{.}0$ rad$/$s$2,$ causing the

DVD to speed up its rotation. What angular distance has the DVD rotated through during the first

two seconds of its motion?

a$)4\mathrm{.}0$ rad

b$)6\mathrm{.}0$ rad

c$)8\mathrm{.}0$ rad

d$)10\mathrm{.}0$ rad

e$)12\mathrm{.}0$ rad
