15. what is the acceleration of an 18kg mass pusheg
9 mass pushed by a 9n force?
16. find the acceleration of the 2kg block in the following diagram.
4n
8n

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

there is no picture in order for this question to be answered

6-3=3

3*3=9

9+12=21

21/3=7

7*8=56

56 is your answer
