98. mmh Two forces, and , act on the 7.00-kg block shown in the drawing. The magnitudes of the forces are F1 = 59.0 N and F2 = 33.0 N. What is the horizontal acceleration (magnitude and direction) of the block?

No mention of friction. Sum of forces are

Since there is no motion in the vertical direction.

Solve for horizontal acceleration

Assuming the standard points to the right above, the – sign tells us the direction is opposite this direction.
