Math Problem Statement

Benda m1 = 3 kg bergerak di atas bidang datar licin. Benda tersebut menumbuk benda m2 yang diam (massa m2 = 2 kg). Setelah tumbukan, m2 bergerak dan mengenai pegas seperti pada gambar hingga pegas memendek 16 cm. Bila konstanta pegas k = 800 N/m dan koefisien tumbukan 1/3, tentukan: a. kecepatan m1 sebelum dan sesudah tumbukan b. kerja oleh gaya pegas. jelaskan secara rinci dengan menggunakan bahasa indonesia
