What is its speed after being pushed 6 m by a force F = 4 N in the direction of motion?
Rasmda ko‘rsatilganidek, massasi m = 1.0 kg bo‘lgan jism ishqalanishsiz gorizontal tekislikda v 0 = 4 m/s boshlang‘ich tezlik bilan harakatlanadi.

Harakat yo‘nalishidagi F = 4 N kuch uni 6 m ga itargandan keyin uning tezligi nimaga teng bo‘ladi?
