1. A 12 weather rocket generates a thrust of 200 . The rocket, pointing upward, is clamped to the top of a vertical spring, 550 / . The spring is anchored to the ground. a. Initially, before the engine is ignited, the rocket sits at rest on the top of the spring. How much is the spring compressed? b. After the engine is ignited, what is the rocket’s speed when the spring has stretched 40 ?

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
