In what kind of exercise would you use the FITT model?
Solnce55 [7]

Answer:

The correct answer is:

Cardio exercise (B)

Explanation:

The frequency, intensity, time and type (FITT) model is a model is planning exercises that incorporate the four elements to be considered when choosing a personal goal and fitness level. Cardiovascular exercises mainly involves aerobic exercises that are aimed at strengthening the heart and lungs and making the working muscles more efficient at the use of oxygen. They also increase stroke volume (volume of blood pumped per minute) and resting heart rate. The following are what the model entails and how they fit best with cardio exercises:

  1. Frequency: This has to do with how often exercises will be done. Depending on the goal cardio exercises are normally recommended as moderate exercises for five or more days a week, and intense cardio for three days a week
  2. Intensity: This has to do with how hard you work during exercises. For cardio exercises, the heart rate monitor, perceived exertion and talk test are done to measure the intensity of the exercise
  3. Time: This has to do with how long each exercise session will last. For cardio exercises, the recommendation is 30 to 60 minutes for each session.
  4. Type: This is the actual activity that is chosen during the sessions, and it is chosen to avoid overuse injuries or weight loss plateus. The type of actvities for cardio includes exercises that are aimed at increasing the heart rate, like running, walking, cycling dancing etc.

Illusion [34]

Answer:

the weight of the rider is 493.53 N

Explanation:

Given the data in the question and as illustrated in the image below,

Tension T = 1900 N

the rider is moving at a constant speed so the net force in the horizontal direction will be 0

In the horizontal direction

F_{sailcos( 30° ) = Tcos ( 17° )

F_{sail = Tcos( 17° ) / cos( 30° )

F_{sail = 1900cos( 17° ) / cos( 30° )

F_{sail = 2098.07 N

Now, In the vertical direction,

F_{sail sin( 30° ) = W + T sin( 17° )

W = F_{sail sin( 30° ) - T sin( 17° )

W = 2098.07sin( 30° ) - 1900sin( 17° )

W = 1049.035 - 555.506

W = 493.53 N

Therefore, the weight of the rider is 493.53 N

A boxer throws a punch with a force of 1,400 N that lasts 0.02 s. What is the impulse of this punch? (1 point) 28 kg⋅m/s 28 kilo
Musya8 [376]

The impulse of the boxers punch is 28 kgm/s.

The given parameters;

  • <em>applied force by the boxer, F = 1400 N</em>
  • <em>time of force action, t = 0.02 s</em>

<em />

The impulse of the boxers punch is calculated as follows;

J = Ft

where;

  • <em>F is the applied force (N)</em>
  • <em>t is the time of force action (s)</em>

The magnitude of the impulse is calculated as follows;

J = 1400 \times 0.02 \\\\J = 28 \ kg m/s

Thus, the impulse of the boxers punch is 28 kgm/s.

A 5.0-kg bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 3.0 m/s2, find the force e
larisa86 [58]

Answer:

65 N

Explanation:

ΣForces = (mass)(acceleration) = all other forces being enacted

The force that the rope exerts is just the tension in the rope caused by the bucket being lifted. I'll take up to be positive and down to be negative, so the tension is an upward force vector and the bucket weight is a downward force vector. By taking into account all the forces involved here, we get the formula:

ΣForces=ma=Tension-mg

  • m is the bucket mass
  • g is gravity pulling down on the bucket, I'm also taking gravity as 10m/s²
  • a is the upward acceleration of the bucket

By isolating Tension we get Tension=ma+mg

Tension = m(a+g)

Tension = 5kg(3+10)m/s²

Tension = (5)(13)N

Tension = 65N
