# Mechanics vectors watch

1. Force F2 = -3i + 5j. Force F2 is the resultant force of all forces acting on an object of mass 5kg. Calculate the acceleration of the object and the change in velocity after 10 seconds
2. Sorry you've not had any responses about this. Are you sure you’ve posted in the right place? Posting in the specific Study Help forum should help get responses.

I'm going to quote in Tank Girl now so she can move your thread to the right place if it's needed.

Since f2 is the resultant force,use F2 = ma to find the acceleration then accel = (change in velocity)/time , equivalent to v = u + at
