Un corp de masă m, așezat pe un plan orizontal fără frecări, este legat de un resort ideal orizontal și, sub acţiunea unei forțe orizontale F, este deplasat la distanţa x, față de poziția de echilibru. Lăsat liber, corpul începe să oscileze armonic. Calculati: a) constanta de elasticitate ka resortului; b) frecvența v a oscilațiilor; c) viteza maximă VM atinsă de corp; d) ecuația de mişcare dacă la momentul inițial corpul este în pozitia de echilibru. Aplicație: m= 250 g; F= 100 N; Xo = 10 mm.

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.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
