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 4 shows a volunteer taking part in the experiment. Figure 4
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:
muscle power = 9.8 × jump height time
One volunteer has a muscle power of 41 W/kg He was in the air for 0.12 s
0 3 . 1
Calculate his jump height.
