What effect does force have on the motion of an object?
xeze [42]

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.

A 0.20-kg block on a horizontal frictionless surface is attached to an ideal massless spring whose spring constant is 360 N/m. T
Angelina_Jolie [31]

Answer:

The answer is 41,4 \frac{m}{s^{2}}

Explanation:

To understand this problem we need to visualize when block is at the equilibrium position and when the displacement is x=-2,3.10^{-2}.

According to Newton's law F=ma, if we find the force applied to the block, we can find the acceleration since we know the mass of the block.

<u>If you compress a spring by x displacement under F force, the spring's force can be found as:</u>

F_{spring} =kx

Therefore F=360\frac{N}{m} .2,3.12^{-2} =8,28N

And to find <u>acceleration</u>:

F=ma → 8,28=0,20a → a=41,4\frac{m}{s^{2}}
