Answer:
1/3n=12
Step-by-step explanation:
The reason why it is 1/3n=12, is because you know that the number in front of n is 1/3. By figuring that out, you have already ruled out 3n=12 and 3n=-12. Finally, you know that 12 is a positive number leaving you with 1/3n=12.
the solution is attached below
the tangential acceleration of car A = -9.8m/s^2
car B = - 13.44 m/s^2
car C = -6.16m/s^2

Answer:
1/72
Step-by-step explanation:
