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

View answer & explanation

Correct answer is A

Total force exerted on the block = (10 - 1)N =9N

Force = mass x acceleration

9 = m x 1.5

m = 9/1.5 = 6kg
