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, v_{T} = 3.0 m/s, T=4.2 s
r = 2.0 m, v_{T} = 3.0 m/s, T=4.2 s
r = 2.0 m, a_{c} = 3.0 m/s, T=4.2 s
r = 2.0 m, F_{c} = 3.0 m/s, T=4.2 s
d = 2.0 m, v_{T} = 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/s^{2}. The tire has a diameter of 0.60 m. List the givens for this problem as they pertain to circular motion.
v_{T} = 2083 m/s^{2}, a_{c = 25 m/s, r = 0.60 m
}
v_{T} = 25 m/s, a_{c = 2083 m/s2, r = 0.60 m
}
v_{T} = 25 m/s, a_{c = 2083 m/s2, T = 0.60 s
}
v_{T} = 25 m/s, F_{c = 2083 m/s2, r= 0.60 m
}
v_{T} = 25 m/s, a_{c = 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, F_{c} = 980 N
T=120 s, r=40 m, F_{c} = 21.9 N
T=60 s, r=20 m, F_{c} = 21.9 N
T=60 s, r=20 m, F_{c} = 980 N
T=60 s, r=40 m, F_{c} = 21.9 N
