Two tug boats are towing a large boat, of mass 22500 kg, back to shore. Tug boat 1 is pulling
with a force of 5500 N at an angle of 35◦ north of the forward motion (similar to Worked
Example 2) and tug boat 2 is pulling with a force of 4907.8 N at an angle 40◦
south of the
forward motion. If the large boat is being pulled with constant velocity, and there is a resistive
force to the motion, then what size is the resistive force?

Respuesta :

Answer:

8265N

Explanation:

If the boat is has a constant velocity, the acceleration must be zero and the sum of all forces must add up to zero. The two forces in the forward direction must match the resistive force:

F = cos(35°)*5500N + cos(40°)*4907.8N
