From the syllabus weighting and how the papers are usually set. The papers below follow it.

Magnetism, induction and AC15%Magnetic fields and forces, Faraday's law and a series RLC circuit are three questions of SP025.
Circular motion, gravitation and rotation12%Banked curves, satellites and rigid body rotation are each a regular SP015 question, about 23 marks together.
Measurements, vectors and kinematics11%Units, dimensions and vectors are paired with linear motion and projectiles in the first two SP015 questions, about 23 marks.
Momentum, forces, work and energy11%Impulse, collisions, Newton's laws on an incline and work, energy and power take two SP015 questions.

(a)The speed

v

of a transverse wave on a stretched string is given by

v = \frac{T}{μ}

, where

T

is the tension and

μ

is the mass per unit length. Use dimensional analysis to show that the equation is homogeneous.[3]

(b(i))A hiker walks 40.0 m in a direction

30. 0^{\circ}

north of east and then 25.0 m due north. Calculate the magnitude of the hiker's resultant displacement.[3]

(b(ii))Determine the direction of the resultant displacement, measured north of east.[2]

(c)Given

A = 3 \hat{i} + 2 \hat{j} - \hat{k}

and

B = \hat{i} - 4 \hat{j} + 2 \hat{k}

, calculate the angle between

A

and

B

(a(i))A car starts from rest and accelerates uniformly at

2.50 m s^{- 2}

for 8.00 s. It then travels at constant velocity for 20.0 s before braking uniformly to rest over a distance of 50.0 m. Calculate the deceleration of the car while braking.[2]

(a(ii))Calculate the total distance travelled by the car.[3]

(b(i))A ball is thrown from the edge of a cliff 30.0 m above flat ground with a velocity of

18.0 m s^{- 1}

35. 0^{\circ}

above the horizontal. Neglect air resistance. Calculate the maximum height of the ball above the ground.[2]

(b(ii))Calculate the time taken for the ball to reach the ground.[3]

(b(iii))Calculate the horizontal distance from the foot of the cliff to where the ball lands.[2]

(a(i))A ball of mass 0.150 kg moving horizontally at

20.0 m s^{- 1}

hits a vertical wall and rebounds along the same line at

15.0 m s^{- 1}

. Calculate the magnitude of the impulse on the ball.[2]

(a(ii))The ball is in contact with the wall for 0.0120 s. Calculate the average force exerted by the wall on the ball.[1]

(b(i))A trolley of mass 2.00 kg moving at

3.00 m s^{- 1}

collides with a stationary trolley of mass 1.00 kg on a smooth track. The trolleys stick together. Calculate their common velocity after the collision.[2]

(b(ii))Calculate the kinetic energy lost in the collision, and state the type of collision.[2]

(c)A 5.00 kg block is pulled up a rough plane inclined at

30. 0^{\circ}

to the horizontal by a force of 50.0 N acting parallel to the plane. The coefficient of kinetic friction between the block and the plane is 0.200. Calculate the acceleration of the block.[4]
