### Instructions
|
|
|
|
|
|
|
|
|
|
Isaac Newton has forgotten his laws of physics and needs your help to animate an object on his game.
|
|
|
|
|
|
|
|
|
|
He must use the Second Law of Motion that states, "when the forces acting on an object are unbalanced, the object will accelerate."
|
|
|
|
|
|
|
|
|
|
This acceleration is dependent upon the force that acts upon the object and the object's mass.
|
|
|
|
|
|
|
|
|
|
So he wants to know what the acceleration of that object is, depending on its properties:
|
|
|
|
|
|
|
|
|
|
- mass of xx
|
|
|
|
|
- Δv of xx
|
|
|
|
|
- Δt of xx
|
|
|
|
|
- force of xx
|
|
|
|
|
- distance xx
|
|
|
|
|
- time xx
|
|
|
|
|
|
|
|
|
|
Create a function named `getAcceleration` that calculates the acceleration of a given object. For example:
|
|
|
|
|
```js
|
|
|
|
|
{
|
|
|
|
|
f: 10,
|
|
|
|
|
m: 5,
|
|
|
|
|
Δv: 100,
|
|
|
|
|
Δt: 50,
|
|
|
|
|
t:1,
|
|
|
|
|
d: 10
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
If it is not possible to calculate it, it must return the string `"impossible"`.
|
|
|
|
|
|
|
|
|
|
### Formulas
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
a = F/m
|
|
|
|
|
a = Δv/Δt
|
|
|
|
|
a = 2d/t^2
|
|
|
|
|
|
|
|
|
|
a = acceleration
|
|
|
|
|
m = mass
|
|
|
|
|
F = force
|
|
|
|
|
Δv = final velocity - initial velocity
|
|
|
|
|
Δt = final time - initial time
|
|
|
|
|
d = distance
|
|
|
|
|
t = time
|
|
|
|
|
```
|
|
|
|
|
|
|
