inn [45]3 years ago
6 0

Answer:

70 W

Explanation:

Power = work / time

P = mgh / t

P = (80 kg) (9.8 m/s²) (3000 m) / (36000 s)

P = 65.3 W

Rounding to one significant figure, the average power output is 70 W.

A seated cable row is an example of which level of training in the NASM OPT model?
Vera_Pavlovna [14]

Answer:

B. Strength

Explanation:

The OPT Model, or Optimum Performance Training Model, is a "fitness training system created by the NASM. The OPT Model is contructed with scientific evidence and principles that progresses an individual through five training phases: stabilization endurance, strength endurance, hypertrophy, maximal strength and power".

On the stabilization level we have the phase 1 called stabilization endurance.

For the level strength part we have 3 phases . Phase 2: Strength endurance , Phase 3: Hypertrophy, Phase 4: Maximal strength. And we can consider the case "A seated cable row" on this the level strength since we need to have some abilities to do this but not enough to stay on the power level since this one is the advancd level.

For the power level we have the last phase called power in order to mantain and conduct high training level programs.

12.Two ice skaters are initially at rest. The 78.2 kg male ice skater pushes his 48.5 kg female partner forward and away from hi
NeTakaya

Answer:

The male skater's velocity is 13.71 m/s.

Explanation:

From the law of conservation of momentum:

m1u1 = (m1 + m2)u2

m1 is the mass of the male skater = 78.2 kg

m2 is the mass of the female skater = 48.5 kg

u1 is the velocity of the male skater as a result of the push

u2 is the velocity with which the male skater pushed away the female skater = 8.46 m/s

u1 = [(78.2+48.5)8.46] ÷ 78.2 = 1071.882 ÷ 78.2 = 13.71 m/s
