A70.0 kg sailor climbs a 28.3 m rope ladder at an angle of 45.0° with the mast. how much work did he do?

He did 10198.5 J of work.

Explanation:

As it is given in the problem, A 70.0 kg sailor climbs a 28.3 m rope ladder at an angle of 45.0° with the mast.

Calculate the force.

Here, m is the mass and g is the acceleration due to gravity.

Put m= 70.0 kg and g=9.8 meter per second.

Use the formula for the work done.

Here, F is the force, s is the displacement and is the angle between the force and displacement.

Put F=686 N, s=28.3 m and  =45.0°.

Therefore, he did 10198.5 J of work.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
