2.0\,\text{kg}

block on a frictionless horizontal surface is simultaneously pulled by two forces:

\vec F_1 = 6\,\text{N}

east and

\vec F_2 = 8\,\text{N}

north. Which of the following vectors best represents the block’s acceleration? a)

directed

53^\circ

north of east c)

5\,\text{m/s}^2

directed

53^\circ

north of east d)

5\,\text{m/s}^2

directed

37^\circ

north of east
