A trailer of mass 1000 kg is towed by means of a rope attached to a car moving at a steady speed along a level road. The tension in the rope is 400 N. The car starts to accelerate steadily. If the tension in the rope is now 1650 N, with what acceleration is the trailer moving?

Question

A trailer of mass 1000 kg is towed by means of a rope attached to a car moving at a steady speed along a level road. The tension in the rope is 400 N. The car starts to accelerate steadily. If the tension in the rope is now 1650 N, with what acceleration is the trailer moving? (A) 1.75 ms -2 (B) 0.75 ms -2 (C) 2.5 ms -2 (D) 1.25 ms -2

Q. A trailer of mass $1000 k g$ is towed by means of a rope attached to a car moving at a steady speed along a level road. The tension in the rope is $400 N$ . The car starts to accelerate steadily. If the tension in the rope is now $1650 N$ , with what acceleration is the trailer moving?

$1.75 m s^{- 2}$

$0.75 m s^{- 2}$

$2.5 m s^{- 2}$

$1.25 m s^{- 2}$

$\Rightarrow (1650 - 400) N = (1000 k g) a^{'}$ or $a^{'} = 1.25 m / s^{2}$
