1. A spring (k = 30 N/m) is compressed 5 cm and launches a 50 g toy straight up. How high does the toy fly?
2. Two blocks are attached together with a piece of string. Block #1 (3 kg) slides along a rough incline of 30º and block #2 (2 kg) hangs off the end of the incline. If the blocks accelerate at 4.5 m/s2 in the directions shown, determine the tension in the string and the coefficient of kinetic friction between block #1 and the incline.
