A tire of radius 34.3 cm turns at 575 rpm.

a) What arc length does a point on the tread of the tire travel in 1.00 minute (answer in radians)?
b) What is the angular speed of the tire in rad/sec?
c) There is a valve-stem located 23.5 cm from the center axis of the tire. What is the centripetal acceleration of this valve stem?

Help ASAP please!! Due tomorrow :(((

angular speed w= 2pi/60 *575 rad/sec

arc length s=w*r*60 cm
centripacc= w^2*.235 N
