Point $A$ of the circular disk is at the angular position $? = 0$ at time $t = 0$ . The disk has angular velocity $?_{0} = 0.30 rad / s$ at $t = 0$ and subsequently experiences a constant angular acceleration $a = 2.1 rad / s^{2}$ . Determine the velocity and acceleration of point $A$ in terms of fixed $i$ and $j$ unit vectors at time $t = 1.3 s$ . Answers:

Question

answers are in i j vAm/s and aAm/s^2

Point

A

of the circular disk is at the angular position

? = 0

at time

t = 0

. The disk has angular velocity

?_{0} = 0.30 rad / s

at

t = 0

and subsequently experiences a constant angular acceleration

a = 2.1 rad / s^{2}

. Determine the velocity and acceleration of point

A

in terms of fixed

i

and

j

unit vectors at time

t = 1.3 s
