A 1200 kg car rolling on a horizontal surface has speed v = 66 km/h when it strikes a horizontal coiled spring and is brought to rest in a distance of 3.3 m. What is the spring constant of the spring?© BrainMass Inc. brainmass.com December 24, 2021, 5:12 pm ad1c9bdddf
v= 66 km/h= 18.33 m/s
mass=m= 1200 Kg
KE=Kinetic energy=1/2 ...
The solution calculates spring constant of the spring.
