Awheel rotates with a constant angular speed ω. which one of the following is true concerning the angularacceleration α of the wheel, the tangential accelerationat of a point on the rim of the wheel, and thecentripetal acceleration ac of a point on the rim?
a)α= 0rad/s2, at= 0m/s2, ac= 0 m/s2
b)α=0 at0 ac= 0
c) α0 at=0 ac=0
d)α=0 at=0 ac0
e)α 0 at0 ac0
