A rock is attached to a 2.0 m long string. The string is swung over your head in a circle at 3.0 m/s. It takes 4.2 seconds for the rock to go around once. List the givens for this problem as they pertain to circular motion.
r = 4.0 m, vT = 3.0 m/s, T=4.2 s
r = 2.0 m, vT = 3.0 m/s, T=4.2 s
r = 2.0 m, ac = 3.0 m/s, T=4.2 s
r = 2.0 m, Fc = 3.0 m/s, T=4.2 s
d = 2.0 m, vT = 3.0 m/s, T=4.2 s
A rock that is stuck in the tread of a tire spins at 25 m/s and experiences an acceleration of 2083 m/s2. The tire has a diameter of 0.60 m. List the givens for this problem as they pertain to circular motion.
vT = 2083 m/s2, ac = 25 m/s, r = 0.60 m
vT = 25 m/s, ac = 2083 m/s2, r = 0.60 m
vT = 25 m/s, ac = 2083 m/s2, T = 0.60 s
vT = 25 m/s, Fc = 2083 m/s2, r= 0.60 m
vT = 25 m/s, ac = 2083 m/s2, r= 0.30 m
A ferriswheel spins around 2 times every 120 seconds. The diameter of the wheel is 40 meters. A 980 N rider has a centripetal force of 21.9 N as he travels around in a circle. List the givens as they pertain to circular motion.
T=120 s, r=40 m, Fc = 980 N
T=120 s, r=40 m, Fc = 21.9 N
T=60 s, r=20 m, Fc = 21.9 N
T=60 s, r=20 m, Fc = 980 N
T=60 s, r=40 m, Fc = 21.9 N
A spaceship with a radius of is spinning constantly at 13 m/s with an acceleration of 9.80 m/s2 takes 16.7 seconds to rotatate around twice. List the givens as they pertain to circular motion.
a = 9.80 m/s2, vT = 13 m/s, T = 8.35 s
a = 9.80 m/s2, vT = 13 m/s, T = 16.7 s
vT = 9.80 m/s2, ac = 13 m/s, T = 16.7 s
vT = 9.80 m/s2, ac = 13 m/s, T = 8.35 s
Fc = 9.80 N, VT = 13 m/s, T = 8.35 s
