Answer:
7840 N
Explanation:
F = Nμ
F = mgμ
F = (2000 kg) (9.8 m/s²) (0.4)
F = 7840 N
i think you should multiply them, the speed is 12 * 3 = 36 m/s
A quasar - <span>Quasars are very distant objects. They are really bright masses of energy and light. The word quasar is actually short for quasi-stellar radio source or quasi-stellar object.
