Initial velocity, u = 4 m/s
acceleration due to gusts of wind = 3 m/s^2
time, t = 1 min = 60 s
Let distance travelled = S
From equation of motion,
Thus, the boat would have traveled 5640m after gusts picked up.

The two cars have same momentum
Explanation:
The momentum of an object is given by the equation
where
m is the mass of the object
v is its velocity
For the car A in this problem,
m = 5 kg
v = 10 m/s
So its momentum is
For car B we have,
m = 10 kg
v = 5 m/s
So its momentum is
Therefore, the two cars have same momentum.
