A 1200-kg car rolling on a horizontal surface has speed v=66km/h when it strikes a horizontal coiled spring and is brought to rest in a distance of 2.2m. What is the spring constant of the spring?
Added by Seamus M.
Step 1
Given: Initial speed v = 66 km/h Convert km/h to m/s: 66 km/h * (1000 m / 1 km) * (1 h / 3600 s) = 18.33 m/s Show more…
