Question

1. A 2000N crate rests on the floor A) how much work is required to move it at constant speed 6m across the floor against a friction force of 300N? B) how much work is done to lift it 6m vertically? 1. A 2000N crate rests on the floor A) how much work is required to move it at constant speed 6m across the floor against a friction force of 300N? B) how much work is done to lift it 6m vertically? A) how much work is required to move it at constant speed 6m across the floor against a friction force of 300N? B) how much work is done to lift it 6m vertically?

Explanation / Answer

A) Work = Force X Distance = 300 N * 6m = 1800 J

B) Work = Force X Distance = mgh = 2000*6 = 12000 J

here mg = 2000N. That is the vertical force.
