A ball connected to a 1.1 m string and is swing in circular fashion. It’s tangential velocity is 15 m/s. What is its centripetal
acceleration?
1 answer:
Answer:
ac = 204 [m/s²]
Explanation:
To solve this problem we must use the following equation that relates the tangential velocity to the radius of rotation.
ac = v²/r
where:
v = tangential velocity = 15 [m/s]
r = radius = 1.1 [m]
Now replacing we have:
ac = (15)²/1.1
ac = 204 [m/s²]

C) 350 m/s N
Explanation:
Velocity is measured in miles per hour or metres per second.
D. velocity includes rate of change and direction
As one moves farther and farther from the Sun, the distance between adjacent planets is greater.
