A boat moves through the water with two

forces acting on it. One is a 2.80×10

3

N

forward push by the motor, and the other is a

1.56×10

3

N resistive force due to the water.

a)What is the acceleration of the 1312.6 kg

boat?

Answer in units of m/s^2

b)If it starts from rest, how far will it move in

17.2 s?

Answer in units of m

c)What will be its speed at the end of this time

interval?

Answer in units of m/s
