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]
Forget about the car's speed. You don't need it.
The tires spin 840 rpm. That's 840 <em>Revolutions per Minute</em> .
There are 60 seconds in 1 minute. So something that happens 840 times in 1 minute happens (840 / 60) times every second.
(840 rev per minute) / (60) = <em>14 revs per second</em> .
