Find the length of the arc intercepted by a central angle of 240 degrees in a circle of radius r equals 9 feet

37.7 feet ( to 1 dec. place )

Step-by-step explanation:

arc length = circumference × fraction of circle

                 = 2π r ×

                 = ≈ 37.7 feet

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
