A block is acted upon by TWO horizontal forces as illustrated in the diagram below. The block accelerates at 1.5\(ms^{-2}\). Calculate the mass of the block.

  • A. 6kg
  • B. 9kg
  • C. 10kg
  • D. 15kg

Correct Answer: A. 6kg

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
