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