If Julian jumps 35 cm and weighs 100 kg, what would happen to his power output if he were to do each of the following?

Increase his body mass by 2 kg and maintain his 35 cm jump height.
Increase his body mass by 2 kg and decrease his vertical jump height by 2 cm.
Decrease his body mass by 2 kg and increase his vertical jump height by 1 cm.

Formula	Power	↑2 kg	↑2 kg ↓ 2 cm	↓2 kg ↑1 cm
Lewis equation (W)	1310
Sayers equation (W)	4600
Harman peak power (W)	7589
Harman average power (W)	1649

Explain how body weight and jump height interact to impact power output.

Increase his body mass by 2 kg and maintain his 35 cm jump height.
Increase his body mass by 2 kg and decrease his vertical jump height by 2 cm.
Decrease his body mass by 2 kg and increase his vertical jump height by 1 cm.

Expert Solution

Ans: The calculations of power output in all three situations of jumps is tabulated below:

Formula	Power	↑2 kg	↑2 kg ↓ 2cm	↓2 kg ↑1 cm
Lewis equation (W)	1310	1336	1273	1277
Sayers equation (W)	4600	4690	4569	4570
Harman peak power (W)	7589	7661	7537	7579
Harman average power (W)	1649	1695	1653	1624

When there is an increase in body mass by 2kg and maintaining same jump height of 35 cm, the power output is slightly increased with some values.
When there is an increase in body mass by 2 kg and decrease in jump height by 2 cm, the power output is slightly decreased with some values.
When there is a decrease in body mass by 2 kg and increase in jump height by 1 cm, the power output is near by same with second condition of ↑2 kg ↓ 2 cm and slightly lowered in comparison to the normal parameters.

By compairing the above power output values in different conditions of body mass and jump height, the following outcomes generated as:

By increasing body mass and making jump height static, there is an increase in power output in comparison to normal.
By increasing body mass and decreasing jump height, there is a decrease in power output in comparison to normal.
By decreasing body mass and increasing jump height, there is a decrease in power output in comparison to normal.

Above all, changes in body mass makes a greater impact on power output as compared to changes in jump height.

A patient arrives at the clinic for his routine dialysis. He weighs in at 108.0 kg. After the patient’s last treatment, he weighed 105.6 kg. His estimated dry weight (EDW) is 105.5 kg. During the treatment, he will receive antibiotics intravenously with 150 mL of normal saline. First, calculate the available weight (AW) in kilograms. AW: What volume of fluid in milliliters must be removed to equal the AW? Assume all fluids have a density of 1.00 g/mL.1.00 g/mL. volume:...

A bungee jumper with mass 64.5 kg jumps from a high bridge. After arriving at his lowest point, he oscillates up and down, reaching a low point seven more times in 44.0 s . He finally comes to rest 20.5 m below the level of the bridge. Part A Estimate the spring stiffness constant of the bungee cord assuming SHM. Part B Estimate the unstretched length of the bungee cord assuming SHM.

A 90 kg student jumps off a bridge with a 10-m-long bungee cord tied to his feet. The massless bungee cord has a spring constant of 390 N/m. You can assume that the bungee cord exerts no force until it begins to stretch. How far below the bridge is the student's lowest point? How far below the bridge is the student's resting position after the oscillations have been fully damped?
