Question

question 8 of 10
the picture below shows a person swinging a yo - yo in a circle.
which vector shows the velocity of the yo - yo at this moment?
a. a
b. b
c. c
d. d

Explanation:

Step1: Recall velocity - direction in circular motion

In circular - motion, the velocity of an object at any point is tangent to the circle at that point.

Step2: Identify the tangent vector

Looking at the diagram, the vector that is tangent to the circle at the position of the yo - yo is vector B.

Answer:

B. B
