(x, y) = (4, -3)

Step-by-step explanation:

Relative to straight east with angles measured CCW, the vector is ...

5∠-36.9° = 5(cos(-36.9°), sin(-36.9°)) = 5(0.8, -0.6) = (4, -3)

$5.03\frac{rad}{sec}$

Step-by-step explanation:

To find the angular velocity divide the revolutions by the time

$\frac{16}{20}=0.8\frac{rev}{sec}$

Remember that

$1\ rev=2\pi \ rad$

Convert rev/sec to rad/sec

$0.8\frac{rev}{sec}=0.8*(2\pi)=1.6 \pi\frac{rad}{sec}$

assume $\pi=3.1416$

$1.6(3.1416)=5.03\frac{rad}{sec}$
