hi this is a simple question but for some reason it's not clicking.(adsbygoogle = window.adsbygoogle || []).push({});

A ball of mass 0.5kg is pulled across a smooth horizontal floor by a horizontal string attached to the dog. The tension in the string is 0.75N. Calculate the acceleration produced. Given the ball starts from rest, determine how far it will move in 2 seconds.

I know how to do the second part but some help would be appreciated on the first bit please.

F resultant = F - T

F-0.75 = ma

a = F- 0.75 /0.5

errm...and then?
