Question

a truck draws a tractor of mass 1000kg at a steady rate of 20m/s on level road. The tension in coulter is 2000N. Power spent on tractor is

Answer 1

Power = Fv
= 2000N × 20m/s
= 40000W
= 40kW

Answer 2

Answer:

Explanation:we know that

P=Fv -equation1

Then, here P=?, F=2000N and v=20m/s

Substituting the values in eq1 we get,

P=2000*20

P=40000W

=40KW
