A spring with spring-constant of 100 N/m is compressed 0.10 m. Assuming this an ideal conservative-force situation, how fast can this spring launch a 0.50 kg mass horizontally on a table (you do not need to take into consideration gravity or other forces)? Question 10 options: a) 0.4 m/s b) 0.7 m/s c) 1.4 m/s d) 4.5 m/s
