Subject: Physics H2
Level: A-Level
Paper: Practice Paper (Mechanics Focus)
Total Marks: 60

Section A: Kinematics and Dynamics

Q1 [2 marks]
Acceleration $a = \frac{v - u}{t} = \frac{12.0 - 0}{4.0} = 3.0\ \text{m s}^{-2}$ .

Q2 [3 marks]
(a) $F = ma \Rightarrow a = \frac{10.0}{2.5} = 4.0\ \text{m s}^{-2}$ . [1]
(b) $s = ut + \frac{1}{2}at^2 = 0 + \frac{1}{2}(4.0)(3.0)^2 = 18.0\ \text{m}$ . [2: 1 method, 1 answer]

(a) $v^2 = u^2 + 2as \Rightarrow 0 = (15.0)^2 - 2(9.8)h \Rightarrow h = \frac{225}{19.6} = 11.5\ \text{m}$ . [1.5]
(b) $t_{up} = \frac{u}{g} = \frac{15.0}{9.8} = 1.53\ \text{s}$ ; total $t = 2 \times 1.53 = 3.06\ \text{s}$ . [1.5]

Q5 [4 marks]
Newton's first law: An object remains at rest or in uniform motion unless acted on by a net external force. [2]
Passenger continues forward due to inertia when car stops; seatbelt provides opposing force. [2]
