A 1.75 kg block slides with a speed of 0.880 m/s on a frictionless horizontal surface until it encounters a spring with a force constant of 787 N/m. The block comes to rest after compressing the spring 4.15 cm.
Find the spring potential energy, U, the kinetic energy of the block, K, and the total mechanical energy of the system, E, for compressions of (a.) 0 cm, (b.) 1.00 cm, (c.) 2.00 cm, (d.) 3.00 cm, (e.) 4.00 cm.
HELP!
I've been using the equations:
spring potential = 1/2*force constant*length^2
kinetic = 1/2*m*v^2
total = Spring + kinetic
