A block of weight 41.8 N is hanging from a rope. The tension in the rope is 24.4 N, pulling upward on the block. What is the magnitude and direction of the acceleration of the block?

I know the direction would be downwards, since the tension of the rope is less than the weight of the block. I'm more so confused about the magnitude. Please help!
Thank you

a = F/m = (41.8-24.4)/ 4.26

Get the mass by undoing mg: 41.8/9.8
