A dart of 0.2-kg mass is loaded 0.05m into a vertically coiled spring (as shown on the right) and then is released. The spring has a stiffness constant k = 800 N/m and negligible mass.
Initial energy stored in spring = J
Final gravitational potential energy of dartwhen spring is relaxed (with the dart still in contact with the spring) = J
Final kinetic energy of dart(at the moment it leaves the spring) = J
Final speed of dart(at the moment it leaves the spring) = m/s
Maximum height of the dart(include the 0.05 meters of the initial spring compression) = m

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.
