Paper 3 is "easily fraudable" once you spot the pattern: either every value you need is already given, or you're expected to know the missing equation from the formula booklet. For each scenario, sort the cards into the right category.
A satellite moves in a circular orbit of radius $7.0\times10^{6}\ \text{m}$ around the Earth (mass $M=5.97\times10^{24}\ \text{kg}$, $G=6.67\times10^{-11}\ \text{N m}^2\text{kg}^{-2}$). Find the satellite’s orbital speed.

A $470\ \mu\text{F}$ capacitor charged to $6.0\ \text{V}$ discharges through a $22\ \text{k}\Omega$ resistor. Find the voltage remaining after $5.0\ \text{s}$.

A mass on a spring oscillates with amplitude $0.050\ \text{m}$ and angular frequency $4.0\ \text{rad s}^{-1}$. Find the speed of the mass when its displacement is $0.030\ \text{m}$.
