| Difficulty | Easy -1.2 This is a straightforward kinematics problem using SUVAT equations with standard values (u=0, s=160m, a=9.8m/s²). It requires only direct application of two basic equations (v²=u²+2as and s=ut+½at²) with no problem-solving insight or conceptual difficulty. The 'state an assumption' part is routine recall (e.g., 'no air resistance'). Significantly easier than average A-level questions. |

A small object, of mass 0.02 kg, is dropped from rest from the top of a building which is160 m high.
\begin{enumerate}[label=(\alph*)]
\item Calculate the speed of the object as it hits the ground. [3]
\item Determine the time taken for the object to reach the ground. [3]
\item State one assumption you have made in your solution. [1]
\end{enumerate}
