Answer:
a. Stored energy is potential energy, and energy of motion is kinetic energy
Explanation:
The correct option is - a. Stored energy is potential energy, and energy of motion is kinetic energy.
Reason -
Potential energy is stored energy, whereas kinetic energy is the energy of moving things.
- Kinetic energy is energy possessed by an object in motion.
- The energy associated with position is called potential energy .
<span>Angular speed = total degree / time
As = 360*(2.5) / 3.0 min (60)
As = 900 deg / 180 s
As =5 Degree / second</span>

i wanna say tranverse if not surface
Explanation:
At t = 0 a truck starts from rest at x = 0 and speeds up in the positive x-direction on..., the time the truck passes the car and the coordinate the truck passes the car is mathematically given as
<h3>What time does the truck pass the car and coordinate does the truck pass the car?</h3>
Generally, the equation for Distance traveled is mathematically given as
By Truck
![d_{T} = v_{T}t + \frac{a_{T}t^{2}}{2}](https://tex.z-dn.net/?f=d_%7BT%7D%20%3D%20v_%7BT%7Dt%20%2B%20%5Cfrac%7Ba_%7BT%7Dt%5E%7B2%7D%7D%7B2%7D)
By Car
![d_{C} = v_{C}t - \frac{a_{C}t^{2}}{2}](https://tex.z-dn.net/?f=d_%7BC%7D%20%3D%20v_%7BC%7Dt%20-%20%5Cfrac%7Ba_%7BC%7Dt%5E%7B2%7D%7D%7B2%7D)
In conclusion, when the conditions the truck passes the car
![d_{T} = d_{C}](https://tex.z-dn.net/?f=d_%7BT%7D%20%3D%20d_%7BC%7D)
Therefore
![v_{t} + \frac{a_{t}t}{2} = v_{C} - \frac{a_{C}t}{2}](https://tex.z-dn.net/?f=v_%7Bt%7D%20%2B%20%5Cfrac%7Ba_%7Bt%7Dt%7D%7B2%7D%20%3D%20v_%7BC%7D%20-%20%5Cfrac%7Ba_%7BC%7Dt%7D%7B2%7D)
![\frac{a_{T}t}{2} = v_{C} - \frac{a_{C}t}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Ba_%7BT%7Dt%7D%7B2%7D%20%3D%20v_%7BC%7D%20-%20%5Cfrac%7Ba_%7BC%7Dt%7D%7B2%7D)
Therefore
![t = \frac{2v_{C}}{a_{T} + a_{C}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B2v_%7BC%7D%7D%7Ba_%7BT%7D%20%2B%20a_%7BC%7D%7D)
differentiation of T
![d_{T} = v_{T}t + \frac{a_{T}t^{2}}{2}](https://tex.z-dn.net/?f=d_%7BT%7D%20%3D%20v_%7BT%7Dt%20%2B%20%5Cfrac%7Ba_%7BT%7Dt%5E%7B2%7D%7D%7B2%7D)

Answer:
An object has potential energy (stored energy) when it is not in motion. Once a force has been applied or it begins to move the potential energy changes to kinetic energy (energy of motion).
EXAMPLE: A rock sitting on the edge of a cliff. If the rock falls, the potential energy will be converted to kinetic energy, as the rock will be moving. A stretched elastic string in a longbow.
