Worked Example — Motion, forces and energy
Worked example: A drone's horizontal speed increases uniformly from 2.0 m/s to 14 m/s in 6.0 s, then remains at 14 m/s for 9.0 s. Calculate the horizontal distance travelled.
Solution
Step 1: During uniform acceleration, use average speed = (initial speed + final speed)/2 = (2.0 + 14)/2 = 8.0 m/s. Step 2: Distance during acceleration = 8.0 × 6.0 = 48 m. Step 3: Distance at constant speed = 14 × 9.0 = 126 m. Step 4: Total distance = 48 + 126 = 174 m.

Worked example: A ray enters a glass tile from air. The angle of incidence is 45° and the angle of refraction is 28°. Calculate the refractive index of the glass.
Solution
Step 1: Use Snell's law for air to glass: n = sin i / sin r. Step 2: Substitute the angles: n = sin 45° / sin 28°. Step 3: Calculate the sine values: 0.707 / 0.469. Step 4: n = 1.51. The refractive index is about 1.5.

Worked example: A resistor is tested. Potential difference / V: 1.5, 3.0, 4.5, 6.0. Current / A: 0.30, 0.60, 0.90, 1.20. Decide whether the resistor is ohmic and find its resistance.
Solution
Step 1: For an ohmic resistor, V is directly proportional to I and resistance is constant. Step 2: Calculate R = V/I using one pair: R = 3.0/0.60 = 5.0 Ω. Step 3: Check another pair: R = 6.0/1.20 = 5.0 Ω. Step 4: Since resistance is constant, the resistor is ohmic.
