Answer:
5558643.69 N
Explanation:
F = Force
v = Velocity = 31.5 knots
Converting to m/s
Power is given by
The forward force is exerted on the ship at this highest attainable speed is 5558643.69 N
Work done by a given force is given by
here on sled two forces will do work
1. Applied force by Max
2. Frictional force due to ground
Now by force diagram of sled we can see the angle of force and displacement
work done by Max =
Now similarly work done by frictional force
Now total work done on sled
To solve this problem divide 60 by 4.6
The answer to this problem is 13 seconds.
