Answer:
When a force acts on an object that is stationary or not moving, the force will cause the object to move, provided there are no other forces preventing that movement. If you throw a ball, you are pushing on it to start its movement. If you drop an object, the force of gravity causes it to move.

Answer:
<h2>20 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 10 × 2
We have the final answer as
<h3>20 N</h3>
Hope this helps you
The <span>x-values equal time (usually in seconds according to physics position vs. time graphs) and the y-values equal distance (usually in meters according to physics position vs. time graphs). I hope the answer helps. Thank you for posting your question here. </span>
Answers:
A) 
B) 22. 5 N
Explanation:
A) Since this situation is related to uniform circular motion, the centripetal acceleration
of the child is calculated by:
Where:
is the speed
is the child's distane to the center (the radius)
Hence:
B) Knowing th centripetal acceleration and the mass
of the child, we can calculate the net horizontal force
by:
