Answer:
C
Explanation:
KE=1/2mv^2
KE=1/2(20)(0.1)^2
0.1^2= 0.01
KE= 1/2(20)(0.01)
KE= 0.1 J

Answer:
Ethan's tangential speed is twice as Rebecca's.
Explanation:
Let be the distance from the center of the platform to Rebecca's horse, Rebecca's tangential speed, the Ethan's tangential speed and the merry-go-round angular speed. The distance from the center of the platform to Ethan's horse is . The angular speed is related to the tangential speed by the equation:
Since the angular speed is the same for Ethan and Rebecca, we have that:
Now, solving for we get:
It means that Ethan's tangential speed is twice as Rebecca's.
