The datalogger records 10 readings every second. The student considered using a temperature probe and datalogger. Explain why it was not necessary to use a temperature probe and datalogger for this investigation.

A scientist investigated how the maximum muscle power of humans varies with age and gender. The scientist asked volunteers to stand on a platform and to jump as high as they could. Figure 18 shows a volunteer taking part in the experiment.

An electronic timer measured the time that the volunteer was in the air.

The muscle power in watts per kg is calculated using the following equation:

One volunteer has a muscle power of 41 W/kg He was in the air for 0.12 s

Calculate his jump height.

Write down the equation which links kinetic energy, mass and speed.

One volunteer had a kinetic energy of 270 J and a speed of 3.0 m/s at the moment he left the ground. Calculate his mass.
