V -20 m Lo Vf m In the Initial configuration (top drawing), on a frictionless horizontal surface, a 2.2 kg block has an initial speed v = 4.9 m/s and encounters a spring. The spring constant is k = 366.0 N/m. Its natural length is Lo = 0.30 m. In the bottom drawing, the block compresses the spring to a new length L= 0.11 m. Part A In the Top configuration, what is the block's initial Kinetic Energy? Keep 2 digits after the decimal point, in Joules Top configuration kinetic energy = Submit Request Answer Part B - In the bottom configuration, what is the spring's potential energy? If you use the "hints", be aware of the grading policy. Keep 2 digits after the decimal point, in Joules View Available Hint(s) bottom configuration spring's potential energy = VE ? J www
