A block is acted upon by TWO horizontal forces ... - WAEC Physics 2018 Question
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 option: a
Total force exerted on the block = (10 - 1) = 9N
Force = mass x acceleration
9 = m x 1.5
m = 9/1.5 = 6kg
