Question

a truck pulls a trailer of mass 1200kg at a steady spead of 10m/s on a level road. the tension in the coupling is 1000n, the power expanded on the trailer is ​

Answer 1

Answer:

2960N

Explanation:

When the towing truck is ascending, the weight force component along the plane, of the truck adds to tension of the coupling.

When the towing truck is ascending, the weight force component along the plane, of the truck adds to tension of the coupling.T′=T+mgsinθ

When the towing truck is ascending, the weight force component along the plane, of the truck adds to tension of the coupling.T′=T+mgsinθT′=1000+1200×9.8×61=1000+1960=2960N

Answer 2

Given:-

$\(sin)\theta = \frac{1}{6}\)$

According to question:-

Since the system moves with a constant velocity, the tension in coupling overcomes the friction as well as the component of weight \(mg\) of the trailer along the plane. Therefore, tension in the coupling is

Given by:-

$\ ( T = f + mgsin\theta = 1000 + 1200\times\;9.8\times\frac{1}{6} = 2960N\)$
