Question

they asked us to use conservation of mechanical energy concepts for this question

. Some racetracks use "compression barriers" which behave like springs to absorb some of the energy of the impact when a car hits the guardrail. If a 1500 kg racecar hits the guardrail at a speed of 70.0 m/s and the compression barrier has a spring constant of 73.5 kN/m, what length would the barrier have to be to stop the car? m = 1500 ky v = 70.0m/s K= 73.5km Ado?
