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

The answer is A - APEX

Option (A)

Explanation:

In case of circular motion, the direction of motion is given by drawing a tangent at that particular point where the direction of motion is to be find.

The direction of motion is same as the direction of velocity. So, the direction of velocity is given by the direction A.

The uniform circular motion is an example of accelerated motion because the direction of velocity keeps on changing constantly, so it has some acceleration.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
