A boat moves through the water with two forces acting on it. One is a 1500 N forward push by the motor, and the other is an 1400 N resistive force due to the water.
(a) What is the acceleration of the 1100 kg boat?
(b) If it starts from rest, how far will it move in 7.0 s?
(c) What will its velocity be at the end of this time?
(a) net force = M * a
Solve for a. The net force is 100 N
(b) X = (a/2)t^2
Use the acceleration "a" from part a.
t = 7 s.
(c) V = a * t
