What is the centripetal acceleration of a point on the perimeter of a bicycle wheel of diameter 70 cm when the bike is moving 8.0 m/s?
2.7 x 10² m/s².
1.8 x 10² m/s².
91 m/s².
2.1 x 10² m/s².
Consider a particle moving with constant speed such that its acceleration of constant magnitude is always perpendicular to its velocity.
It is moving in a parabola.
It is moving in a circle.
None is definitely true all of the time.
It is moving in a straight line.
