A block is acted upon by TWO horizontal forces as illustrated in the diagram above. The block accelerates at 1.5\(ms^{-2}\). Calculate the mass of the block.
-
6kg
- 9kg
- 10kg
- 15kg
The correct answer is: A
Explanation
Total force exerted on the block = (10 - 1)N =9N
Force = mass x acceleration
9 = m x 1.5
m = 9/1.5 = 6kg
