Q1. A cyclist of mass 78 kg rides a bicycle of mass 12 kg. She free-wheels down a slope inclined at
4.5° to the horizontal at a constant speed of 6.5 m s⁻¹, as shown in Figure 1.
Figure 1 (Diagram shows cyclist on slope, angle 4.5° indicated)
(a) State why the cyclist travels at constant speed despite the component of her weight acting down
the slope. [2 marks]
,(b) She stops pedalling and applies the brakes, bringing the bicycle to rest from a speed of 6.5 m
s⁻¹ in a distance of 8.2 m.
Calculate the average braking force required. Assume the resistive forces remain constant at 25 N.
[5 marks]
Q2. Figure 2 shows stress-strain graphs for two materials, X and Y, up to fracture.
Figure 2 (Graph: Stress (MPa) vs Strain. Material X: steep linear then fracture at ~2% strain.
Material Y: less steep linear, yield point at ~1%, plastic deformation to ~15% strain then fracture)
(a) State the meaning of the term ultimate tensile strength. [2 marks]
(b) A structural engineer must select a material for a bridge support that must withstand high static
loads but undergo visible deformation before fracture to provide warning of failure.
Determine, with reference to the graphs, which material is more suitable. Calculate the Young’s
modulus for your chosen material. [5 marks]
Q3. A student investigates the properties of a cell of unknown EMF and internal resistance. She
connects the cell in series with a variable resistor and an ammeter. A voltmeter is connected across
the cell. She obtains the following data:

(a) State the relationship between EMF (ε), terminal potential difference (V), current (I) and internal
resistance (r). [2 marks]
(b) Plot a graph of V against I on the grid provided. Determine the EMF and internal resistance of
the cell. [4 marks]
(Graph grid provided: V from 1.0 to 1.6 V, I from 0 to 100 mA)
