If a spring is compressed 2.0 cm from its equilibrium position and then compressed an additional 2.0 cm, how much more work is done in the second compression than in the first? Explain. A hot-air balloon ascends at a constant rate. (a) The weight of the balloon does (1) positive work, (2) negative work, (3) no work. Why? (b) A hot-air balloon with a mass of 500 kg ascends at a constant rate of 1.50 m/s ...A spring has a spring constant of 30 N/m. How much work is required to stretch the spring 2.0 cm from its equilibrium position? A particular spring has a force constant of 2.5 x 103 N/m.
