A parachutist has reached a first terminal velocity before opening a parachute. Consider the motion from just before opening until a new terminal velocity is reached.
Explain the changes in resultant force, acceleration and speed throughout this sequence.

Answer and supported method checks
A manufacturer claims a rubber luggage strap is more suitable than a steel spring for repeated stretching under load. A fair comparison must use the same maximum applied force and check whether each sample returns to its original length.
Plan an investigation to compare how extension depends on force for the strap and spring, and test whether they recover their original lengths after repeated loading.
A road-safety trial compares two drivers. Driver A is alert on worn tyres; driver B is tired on new tyres. Both drive at the same speed on the same road. Only their final stopping distances are recorded.
Evaluate whether this trial can show how tiredness affects stopping distance. Explain a better investigation that avoids driving while tired.

An imaging leaflet gives typical effective doses: one chest X-ray 0.020 mSv and one CT examination 4.0 mSv. These values are supplied; you do not need to recall dose units.
.1
Calculate the number of chest X-rays giving the same listed total dose as one CT examination.
[2 marks]
.2
Explain why the dose comparison alone cannot decide whether a patient should have the CT examination.

Two sealed objects are the same size. One contains a permanent bar magnet and the other an unmagnetised iron bar. You have a third, labelled bar magnet, a plotting compass and paper.
Plan a sequence of tests to distinguish the objects and map the field of the permanent magnet.
