To change my friends mind, after they've already said weather predictions are just guesses, I would say they are correct, but not only to they use guesses to predict what will happen, but they also, before hand, use atmospheric tools. They then predict from the data collected. They do both.
Answer:
False they are producers and they don' eat anything only produce and provide

Explanation :
It is given that,
Mass of the car, m = 1000 kg
Force applied by the motor, ![F_A=1000\ N](https://tex.z-dn.net/?f=F_A%3D1000%5C%20N)
The static and dynamic friction coefficient is, ![\mu=0.5](https://tex.z-dn.net/?f=%5Cmu%3D0.5)
Let a is the acceleration of the car. Since, the car is in motion, the coefficient of sliding friction can be used. At equilibrium,
![F_A-\mu mg=ma](https://tex.z-dn.net/?f=F_A-%5Cmu%20mg%3Dma)
![\dfrac{F_A-\mu mg}{m}=a](https://tex.z-dn.net/?f=%5Cdfrac%7BF_A-%5Cmu%20mg%7D%7Bm%7D%3Da)
![a=\dfrac{1000-0.5(1000)(9.81)}{1000}](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7B1000-0.5%281000%29%289.81%29%7D%7B1000%7D)
![a=-3.905\ m/s^2](https://tex.z-dn.net/?f=a%3D-3.905%5C%20m%2Fs%5E2)
So, the acceleration of the car is
. Hence, this is the required solution.
