\huge{\mathfrak{\underline{\underline{Correct\:\:Question}}}}

A truck of mass 1000 kg is pulling a TRAILER of mass 2000kg as shown the retarding force on the truck is 500 N. And that on the trailer is 1000 N, the truck engine EXERT a force of 6000 N.

(i) Calculate the acceleration of the truck and trailer .

(ii) The TENSION in connecting rope.

\huge{\underline{\mathfrak{Answer:}}}

\rule{200}{2}

Let a be the acceleration of the truck and the trailer.

(1) 6000 - (500 + 1000)

» (1000 + 2000)a

» THEREFORE, a = 4500/3000

» 1.5 ms-² ............[Answer]

(2) Let T be the tension in the connected rope.

T = 2000a + 1000

» 3000 + 1000

» 4000 N ...........[Answer]

\rule{200}{2}
