Question 5 1 pts Calculate the mechanical power output in Watts (W) when a subject pedals at a rate of 90 RPM for 45 min. against a 3.8 kp resistance on the cycle ergometer. Every revolution of the flywheel is 6 m. There are 9.81 Joules per kpm and there are 60 seconds (s) per minute. In addition, there is 1 Joule per second (J/s) in every W. 309.0 W 210.0 W 34.2 W 335.5 W Question 6 1 pts Calculate the mechanical power output in Watts (W) when a subject pedals at a rate of 80 RPM for 20 min. against a 3.2 kp resistance on the cycle ergometer. Every revolution of the flywheel is 6 m. There are 9.81 Joules per kpm and there are 60 seconds (s) per minute. In addition, there is 1 Joule per second (J/s) in every W. 235.4 W 31.8 W 214.1 W 251.1 W

Question 7 1 pts Calculate the total amount of mechanical work output in kilocalories (kcal) when a subject pedals at a rate of 75 RPM for 45 min. against a 3.6 kp resistance on the cycle ergometer. Every revolution of the flywheel is 6 m. There are 9.81 Joules per kpm and there are 60 seconds (s) per minute. In addition, there is 1 Joule per second (J/s) in every W and there are 4,186 J per kcal. 170.8 kcal 135.0 kcal 28.5 kcal 151.9 kcal
