A rifle fires a 2.01 10-2-kg pellet straight upward, because the pellet rests on a compressed spring that is released when the trigger is pulled. The spring has a negligible mass and is compressed by 9.45 10-2 m from its unstrained length. The pellet rises to a maximum height of 6.03 m above its position on the compressed spring. Ignoring air resistance, determine the spring constant.

The value of spring constant is 266.01

Explanation:

Given:

Mass of pellet kg

Height difference of pellet rise m

Spring compression m

From energy conservation law,

Spring potential energy is stored into potential energy,

Where spring constant,

Therefore, the value of spring constant is 266.01

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

technology is the application of the knowledge gained by science.
