Answer:
The resultant velocity of the boat and its direction is 6.96 m/s in east direction.
Explanation:
Given that,
Velocity of boat = 7.3 m/s in east direction
Velocity of current = 0.34 m/s in west from the east
The velocity of current is in opposite direction of the velocity of boat.
So, The resultant velocity of the boat will be
The resultant velocity = Velocity of boat - velocity of current
The direction of the boat in east direction.
Hence, The resultant velocity of the boat and its direction is 6.96 m/s in east direction.

Answer:
T=7.4 N hence T<30 N
Explanation:
The figure is likely to be similar to the one attached. Writing the equation for forces we have
F-T=Fa/g where F is the force, T is tension, a is acceleration and g is acceleration due to gravity. Substituting the figures we have the first equation as
30 N - T = (30/9.81)a
Also, we know that T=F*a/g and substituting 10N for F we obtain the second equation as
T = (10/9.81)a
Adding the first and second equations we obtain
30 = 4.077471967
a Hence
and T=a hence
T is approximately 7.4 N
