1. a = F/m = (2100-1800)/1200
2. d = (1/2) a t^2 = 50 a
3. v = a t = 10 a
A motor pushes a boat through the water with the force of 2100 N; the water creates a resistance force of 1800 N.
What is the acceleration of 1200 kg boat?
(Do I use force equals mass times acceleration? 2100=1200a)
If it starts from rest how far will it move in 10 seconds?
(Do I take the acceleration and multiply it by 10?)
What will it's velocity be at the end of this time period?
I'm completely confused on this one

NET force = 2100 - 1800 !!!!!!!
