Question

A truck tows a trailer of mass 1200 kg at a steady speed of 10 m/s on a
level road. The tension in the coupling is 1000 N, the power expanded on
the trailer is​

Answer 1

Answer:

10000 watt

Explanation:

We have been given

Tension in the coupling is  10000 N

And speed of V = 10 m / s

And truck trailer mass is  1200 kg

Now  we know that

Power expanded on the trailer is  = Tension in coupling × speed

Power expanded on the trailer is = 1000 × 10

Power expanded on the trailer is = 10000 watt

 

Answer 2

Answer:

P=F×S

=1000×10

=10000

$= 10 {}^{4} \: watt$
