Question

A truck engine of mass 5000 kg pulls a trailer of mass 1000 kg along a level track
at an acceleration of 0.10 m s-2 . The resistances are 10 N per 1000 kg
for the truck engine and 5 N per 1000 kg for the trailer.

Calculate the
(i) tension in the connecting tow bar between the engine and the trailer;
(ii) forward thrust exerted by the engine.​

Answer 1

Answer:

Answer

(A) . Let a be acceleration of truck and the trailer

Fnet=ma

6000 - (500+1000) = (1000+2000)a

therefore

a=

3000

4500

=1.5m/s

2

(B) let T be the tension in the connected rope.

T=2000a+1000

=3000+1000

=4000N
