1. (20 points) In flagrant violation of lab procedure, one of your group members has taken the spring from our spring lab, attached a 50g mass to it, and has started twirling it in a horizontal circle such that the spring is at an angle of 40 below the horizontal. You know from your data that the spring has an unstretched length of 20 cm and a spring constant of 5 N/m. Determine how much the spring stretches when the mass is twirled at this angle, and determine how many times the mass spins around in a complete circle during a 10s time period. 0000000 5. You and your friend are having an impromptu snowball fight, they just don't know it yet. You make a 500 g snowball made of ice at 0C and, after accounting for the effect of air resistance, expertly throw it from the bottom of a 10m-tall hill with a throwing speed of 30 m/s. The snowball squarely hits your friend at the top of the hill, at which point it was traveling at 10m/s before hitting them. How much of the snowball melted by the time it hit your unsuspecting friend?
