Answer:
a.
Explanation:
Use accleration formula,
![a = \frac{v _{f} - v _{i}}{t}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7Bv%20_%7Bf%7D%20-%20v%20_%7Bi%7D%7D%7Bt%7D%20)
The initial velocity and final velocity is at zero. and t=10
So we got
![\frac{0}{10} = 0](https://tex.z-dn.net/?f=%20%5Cfrac%7B0%7D%7B10%7D%20%20%3D%200)
so
![a = 0](https://tex.z-dn.net/?f=a%20%3D%200)
a is the answer
Answer:
continuous change in position with respect to time
Explanation:
Velocity is defined as the rate of change of the position of an object with respect to its time.
It's the vector quantity of speed as it has both magnitude and direction.
Hope this helps :)

Answer:
the potential energy is zero, and the kinetic energy must be maximum
F = 0
Explanation:
In this exercise you are asked to complete the sentences of a simple harmonic movement of a mass-spring system.
In this system mechanical energy is conserved
at the most extreme point the carousel potential energy is
K_e = ½ k x²
the kinetic energy is zero for that stopped.
At the equilibrium point
the spring elongation is x = 0 so the potential energy is zero
and the kinetic energy must be maximum since total energy of the system is conserved
the spring force is
F =- k x
as in the equilibrium position x = 0 this implies that the force is also zero
F = 0
