Answer all questions. You may use a calculator. Take $g = 10\,\text{N/kg}$. Show your working. This paper samples Topics 1–5 (Double Award only).
1
Topic 1 A $900\,\text{kg}$ van is driven out of a workshop. The driving force is $2700\,\text{N}$ and resistive forces total $900\,\text{N}$.
(a) Calculate the resultant force.
[2]
(b) Calculate the acceleration. State the unit.

Topic 2 An electric drill is labelled $230\,\text{V}$, $1840\,\text{W}$.
(a) Calculate the current in the drill.
[2]
(b) The drill is used for $2.0\,\text{minutes}$. Calculate the charge that flows. Use $Q=It$.

Topic 5 An oil drum contains oil of density $800\,\text{kg/m}^3$. The depth of oil is $1.5\,\text{m}$.
(a) Calculate the pressure due to the oil at the bottom of the drum.
[3]
(b) State what happens to this pressure if the drum is taken to a planet where $g$ is larger, and explain using $p=h\rho g$.
