Does the car's tire turn 65 because the car reduces the standard deviation from 90.0 kmph to 40.0 kmph? 3
The car's tire represents 65 revolutions, while the car reduces the standard deviation from 90.0 kmph to 40.0 kmph. The diameter of the tire is 0.90 meters.
(a) What is angular velocity?
_____ rad / s2
(B) If the vehicle slows down at the same speed, will it take longer to stop?
_____ s
Help.
65 rounds 408.4 red.
Angular velocity changes from 55.56 rad / s to 24.7 rad / s
Need help from
wfinal 2 = winital 2 2a (theta)
24.7 2 = 55.56 2 2 (408.4) a
a = 3.03 rad / s 2
B) 24.7 = 3.03 t
t = 8.15 seconds.
