Huu hapa ni ufumbuzi wa swali la 3: a) Eleza mwendo kati ya O na A Step 1: Angalia grafu kati ya O na A. Grafu inaonyesha kasi ikiongezeka kutoka 0\, m/s hadi 12\, m/s kwa mstari ulionyooka. Mwendo kati ya O na A ni kasi inayoongezeka kwa usawa (uniform acceleration). b) Eleza mwendo kati ya A na B Step 1: Angalia grafu kati ya A na B. Grafu inaonyesha kasi ikiwa 12\, m/s na haibadiliki. Mwendo kati ya A na B ni kasi isiyobadilika (uniform velocity). c) Bainisha mchapuko kati ya B na C Step 1: Tambua pointi B na C kutoka kwenye grafu. Kwenye B, muda t_B = 100\, s na kasi v_B = 12\, m/s. Kwenye C, muda t_C = 120\, s na kasi v_C = 0\, m/s. Step 2: Tumia fomula ya mchapuko. Mchapuko a hutolewa na mabadiliko ya kasi kugawanya kwa mabadiliko ya muda: a = (v_C - v_B)/(t_C - t_B) Step 3: Badilisha thamani na ukokotoe. a = 0\, m/s - 12\, m/s120\, s - 100\, s a = -12\, m/s20\, s a = -0.6\, m/s^2 Mchapuko kati ya B na C ni -0.6\, m/s^2.
