hi this is a simple question but for some reason it's not clicking.
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?
