Problem

1200\,\text{kg}

car is supported by four identical coil springs. During a large bump, each spring compresses by

0.15\,\text{m}

. Only

60\%

of the energy stored in the springs is available to raise the car’s centre of mass. Determine the minimum spring constant

k

for each coil if the car’s centre of mass must rise at least

0.10\,\text{m}

after compression. a)

1.74\times10^{5}\,\text{N/m}

4.4\times10^{4}\,\text{N/m}

2.6\times10^{4}\,\text{N/m}

6.5\times10^{4}\,\text{N/m}
