Aride at an amusement park moves the riders in a circle at a rate of 6.0 m/s. the radius of the ride is 9.0 meters. which of the following shows the direction of the acceleration of the riders?
a
b
c
d

Answer with explanation:

It is given that , ride at an amusement park moves the riders in a circle at a rate of 6.0 m/s.

Radius of Circle = 9.0 meters

Acceleration is rate of change of velocity,which will be perpendicular to radius vector.

Also, in terms of mathematics, line from center that is radius , to point of contact that is tangent line ,which is on the circle are perpendicular to each another.

→r(radius vector) ⊥  a(Acceleration vector).

So, In option A, Radius vector is Perpendicular to acceleration of riders.

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
