Correct answer choice is :
A) Toward the center of a circle, which changes the direction of motion but not the speed.
Explanation:
A centripetal force is a force that gives a body support a curved way. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instant center of the curve of the path. The direction of the net energy is in the same direction as the acceleration. So for an object traveling in a circle, there must be an internal force acting upon it in order to create its internal acceleration. This is seldom related to as the centripetal force demand.
Answer:
Deceleration
Explanation:
The amount by which a speed or velocity decreases
Explanation:
The tangential speed of Andrea is given by :
Where
r is radius of the circular path
ω is angular speed
The merry-go-round is rotating at a constant angular speed. Let the new distance from the center of the circular platform is r'
r' = 2r
New angular speed,
New angular speed is twice that of the Chuck's speed.
