Asked by Paige

1.) If the penny is at a radius of 6.00 cm spinning at a speed of 3.50 rad/sec. What is the centripetal acceleration of the penny in m/s2? Enter your answer to three significant figures.


Answered by Damon
Ac = R omega^2
R = 0.06 meter
omega = 3.5

That assumes you want Ac at the rim of the penny.
Answered by Paige
linear speed: 0.2100
centripetal acceleration: 0.7350
tangential acceleration: 0.0132

How to find total acceleration in m/s^2?
Answered by Damon
they are perpendicular
|A| = sqrt (At^2 + Ac^2)
