Here,

\large\rm\red{m} = 1000kg

\large\rm\pink{v} = 18km h {}^{ - 1} = 18 × \large\frac{5}{18} ms { }^{ - 1}  = 5ms {}^{ - 1}

\large\rm\purple{k} = 6.5 × 10³N m  {}^{ - 1}

  • At maximum compression χm , the kinetic energy of the car is converted entirely into the potential energy of the spring.

\large\frac{1}{2} mv² = \large\frac{1}{2} kx²m or xm = \large\sqrt{\frac{m}{k}}v

  • Substituting the given values we get,

\large\bf\green{xm} = \large\sqrt{ \frac{1000kg}{6.25 \times 10 {}^{2} n \: m{}^{ - 1} } } × 5ms  {}^{ - 1}

= 0.4 × 5m = \large\red{2m}

\large{\underline{\overline{\blue{\bold{\boxed{\sf{Final\:Answer\:}}}}}}}

  • The maximum compression of the spring is 2m.

Hope it Helps uh Dear!! ❤
