On a frictionless track, a 0.55 kg cart is traveling at 0.70 m/sec when it runs into a spring that is anchored to the end of the track. The spring was 6 cm long to start with but is compressed down to only one-third that length in bringing the cart to rest.
what is the original kinetic energy of the cart as it approached the spring?
what is the spring constant?
what was the maximum magnitude of the force exerted by the spring on the cart?
Determine the maximum percent uncertainty it will produce in this experiment if we did not align the apparatus to minimize its effects
