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.
