The number 749 can be decomposed using place value, represented as 700 + 40 + 9, or by simple addition as 740 + 9 or 700 + 49. Each method highlights different aspects of the number. Understanding these different decompositions illustrates the flexibility of representing numbers in mathematics.

Diketahui:Kecepatan awal (v₀) = 10 m/sPercepatan (a) = -2 m/s²Kecepatan akhir (v) = 0 m/s (karena berhenti)Gunakan rumus:v = v₀ + a × t0 = 10 + (-2) × t0 = 10 - 2t2t = 10t = 10 ÷ 2t = 5 detikJadi, waktu yang dibutuhkan benda untuk berhenti adalah 5 detik
