# A \( 240 \) \( \text{kg} \) block is dropped from \( 3.0 \) meters onto a spring, compresses the spring and comes to rest. a) Draw the bar charts for the frictionless system including the block, spring and Earth. b) How fast was the block going just before it struck the spring? b) If the block compressed the spring \( 50.0 \) cm, what is the total elastic potential stored in the spring? c) Determine the spring constant.

A \( 240 \) \( \text{kg} \) block is dropped from \( 3.0 \) meters onto a spring, compresses the spring and comes to rest.

**Part a)** How fast was the block going just before it struck the spring? *(3 points)*

**Part b)** If the block compressed the spring \( 50.0 \) cm, what is the total elastic potential energy stored in the spring? *(3 points)*

**Part c)** Determine the spring constant. *(3 points)*
