Agolfer’s arm rotates 1/2 of a revolution in 1/10 of a second. if the angular displacement is measured in radians, which statements are true? check all that apply.

the angular velocity is 10π rad/sec.
the angular velocity is 10π rad/min.
the angular velocity is 60π rad/min.
the angular velocity is 600π rad/sec.
the angular velocity is 600π rad/min.

The angular velocity is 10π rad/s or 600 rad/min.

Step-by-step explanation:

angular velocity = angle/time

0.5 revolution = 0.5 × 2π = π rad

ω = θ/t = π rad/0.1 s = 10π rad/s

Convert time to minutes

ω = 10π rad/1 s × (60 s/1 min) = 600π rad/min

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
