Question 5 1 pts A horizontal spring with spring constant 30 N/m is compressed by 5 cm by a 10 gram mass. After the mass is released, it accelerates due to the potential energy of the spring. Use conservation of energy to determine what speed the 10 gram mass reaches after being pushed by the spring. Answer in units of m/s and round to 3 significant figures.
