12a-(4b+4a)-b
12a-4b-4a-b
=> 8a-5b
Answer:
Force= Mass×Accelaraion
F=m×a
But as The unit of accelaration is given miles per hour and the SI is meters per second sqaure we have to convert 10mph to m/s²
Thus, we have 10mph = 4.47 meters per second square. (i converted using scientific calculator)
So now we have,
2000N= m×4.47m/s²
= 2000/4.47m/s²=m
= 447.42
Thus the mass of the object is 447.42 (i am not sure of units)
14.6969385 lies between 14 and 15.
I hope it's right! Virtually slap me if it is not.
Answer:
The given statement is true.
