Explanation:
Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity v and has the magnitude ac=v2r;ac=rω2 a c = v 2 r ; a c = r ω 2 .

Explanation:
Vector A points up
Vector B points right
The combination must be both up and right which is C
Distance is 90km,time 1 hr
