Answer:

The five components of physical fitness are cardiovascular endurance, muscular strength, muscular endurance, flexibility and body composition, according to Fit Day.

cardiovascular endurance:

Cardiorespiratory endurance:

is the level at which your heart, lungs, and muscles work together when you're exercising for an extended period of time. This shows how efficiently your cardiorespiratory system functions, and is an indicator of how physically fit and healthy you are.

muscular strength:

Muscular strength is defined as the maximum amount of force that a muscle can exert against some form of resistance in a single effort.

muscular endurance:

Muscular endurance is the ability of your muscle or muscle groups to withstand repeated contractions for an extended period.

flexibility and body composition:

Stretching before and after activities will help to improve flexibility. The sit-and-reach and the trunk lift are two tests used to measure flexibility. Body Composition is the percentage of body weight that is fat compared to other body tissue, such as bone and muscle.

A skier accelerates down the hill at 3m/s2 how fast is he going in 4 seconds

almond37 [142]

Answer:

Explanation: simple kinematics

we suppose that initially vo= 0 so if the skier moves 4s :

vf = vo +at = 0 + 3*4 = 12 m/s

Answer:

$-22.7 m/s^2$

Explanation:

This is a uniformly accelerated motion, so we can determine the deceleration of the car by using a suvat equation:

$v^2-u^2=2as$

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance covered

For the car in this problem,

u = 27.8 m/s

v = 0

s = 17 m

Solving for a, we find the acceleration:

$a=\frac{v^2-u^2}{2s}=\frac{0-27.8^2}{2(17)}=-22.7 m/s^2$

You build a grandfather clock, whose timing is based on a pendulum. You measure its period to be 2s on Earth. You then travel wi

Elenna [48]

Answer:

$\frac{g_{2}}{g_{1}} = \frac{1}{4}$

Explanation:

The period of the simple pendulum is:

$T = 2\pi\cdot \sqrt{\frac{l}{g} }$

Where:

$l$ - Cord length, in m.

$g$ - Gravity constant, in $\frac{m}{s^{2}}$ .

Given that the same pendulum is test on each planet, the following relation is formed:

$T_{1}^{2}\cdot g_{1} = T_{2}^{2}\cdot g_{2}$

The ratio of the gravitational constant on planet CornTeen to the gravitational constant on planet Earth is:

$\frac{g_{2}}{g_{1}} = \left(\frac{T_{1}}{T_{2}} \right)^{2}$

$\frac{g_{2}}{g_{1}} = \left(\frac{2\,s}{4\,s} \right)^{2}$

$\frac{g_{2}}{g_{1}} = \frac{1}{4}$

2. You decide to lift a 25 kg box to a height of 3 meters. How much work will you do while moving

nadya68 [22]

Answer:

W = 735.75[J]

Explanation:

Work is defined as the product of force by distance. Therefore we can use the following equation.

$W=F*d$

where:

W = work [J] (units of Joules)

F = force [N] (units of Newtons)

d = distance = 3 [m]

But first, we must determine the force that is equal to the product of mass by gravity (weight of the body).

$F=m*g\\F=25*9.81\\F=245.25[N]$

$W=F*d\\W=245.25*3\\W=735.75[J]$
