A car starts from rest and reaches 24 m/s in 6 s. Find (i) the average acceleration and (ii) the distance travelled in these 6 s.
Answer: • u = 0, v = 24 m/s, t = 6 s.
• a = (v − u)/t = 24/6 = 4 m/s².
• s = ut + ½at² = ½ × 4 × 6² = 72 m.

Derive/state the three equations of motion and explain what each quantity means.
Answer: The three equations of motion (uniform acceleration) are:
• v = u + at
• s = ut + ½at²
• v² = u² + 2as
Where:
• u = initial velocity
• v = final velocity
• a = acceleration
• t = time interval
• s = displacement
