## Question:

A car is hauling an 89 kg trailer, to which it is connected by a spring. The spring constant is 2100 N/m. The car accelerates with an acceleration of 0.29 m/s{eq}^2 {/eq}. By how much does the spring stretch?

## Spring:

Spring is metallic circular coil which is elastic in nature which stores mechanical energy. A spring, when displaced from its equilibrium position or original position will exert a restoring force opposite the direction of motion of an object attached in order to return to its original positional position. The magnitude of this force is proportional to the length by which the spring was displaced.

Given:

{eq}m_t = 89 \ kg {/eq} Mass of the trailer

{eq}k = 2100 \frac {N}{m} {/eq} Spring constant

{eq}a = 0.29 \frac {m}{s^2} {/eq}...
