Four forces act concurrently on a block on a horizontal surface as shown in the diagram
below.
As a result of these forces, the block
A) accelerate to the right
B) accelerate to the left
C) moves at constant speed to the right
D) moves at constant speed to the left

i think if it were me i whould divide 300 dide 15

step-by-step explanation:
