Kuvvet-Zaman Grafiği ve Hız Değişimi

16. İlk hızı $15 m/s$ olan $8 kg$ kütleli cisme uygulanan net kuvvetin zamana bağlı değişim grafiği şekildeki gibidir. Buna göre, cismin 16. saniyedeki hızı kaç $m/s$ olur?

Soruda görsel içerik var: A Force (F) vs Time (t) graph is shown on a Cartesian coordinate system. The vertical axis represents Force (F) in Newtons, and the horizontal axis represents Time (t) in seconds. The graph starts at (0,0), rises linearly to (4,10), stays constant at F=10 until t=8, then decreases linearly, crossing the t-axis at t=12 and reaching a value of F=-20 at t=16. Some handwritten notes are on the graph calculating areas under the curve: a triangle from 0-4s ($20 N \cdot s$), a rectangle from 4-8s ($40 N \cdot s$), a triangle from 8-12s ($20 N \cdot s$), and a negative triangle from 12-16s ($-40 N \cdot s$).
