A) 0.0 N
B) 69.5 N
C) 0.77 N
D) 8.58 N

Quizplus · Accepted Answer

The force required to move an object in a circular path at a constant speed is given by the centripetal force formula: $ F = \frac{mv^2}{r} $, where $ m $ is the mass of the object, $ v $ is the velocity, and $ r $ is the radius of the circle. Plugging in the given values: $ F = \frac{90.0 \times (8.10)^2}{85.0} \approx 69.5 \, \text{N} $.
