My Fitness Goals: (List your specific and general goals)

Leokris [45]

-Try one new workout every month. Keeping the same exact routine when it comes to your fitness is never a good thing.

-More water
With any diet, the most important thing to remember is to stay hydrated. Drinking water will support your body with digestion, transporting nutrients to your bones and muscles, and even improving cognitive function.
Ideally, you want to drink about half your body weight in ounces per day, i.e. if you weight 150 pounds, you should drink 75 ounces of water a day.

-Stretching
The benefits are vast and the repercussions of failing to stretch can be dramatic.
Do yourself a favor and always stretch before and after a workout. This will promote a healthy cool down, improve flexibility, and reduce next day aches. Failure to stretch can lead to injures and muscle damage.

-Body Fat
This may seem like an obvious one, but it is one of the most important steps to a healthier you. Reducing your body fat has a lot of benefits such as:

Improved joints and tendons
Lowered risk of diabetes
Reduced risk of heart disease
Reduced inflammation
Better performance and endurance
Improved appearance and confidence
Better hormonal profiles in your body
Remember, it is not a race to see how quickly you can decrease your body fat. Healthy weight loss is around 1-2 pounds a week for your fitness goals.[2]

Crash dieting or pushing yourself too much in the gym can lead to you achieving an unrealistic target, and you may find yourself gaining all the weight you have lost.

Think of it as a lifestyle, and take it slow and steady.

A 0.5 kg block is attached to a spring (k = 12.5 N/m). The damped frequency is 0.2% lower than the natural frequency, (a) What i

Tju [1.3M]

Answer:

a) 1.58 kg s^{-1}

b) x_m e^{-1.58t} x_m is initial amplitude

c) 5 kg s^{-1}

Explanation:

given data:

mass =0.5 kg

k = 12.5 N/m

from the data given

a) $w_d = w_o - \frac{0.2}{100}w_o$

$= w_o - 0.002w_o = 0.99w_o$

$w_d = \sqrt{\frac{k}{m} - \frac{b^2}{4m^2}$

$0.998w_o = \sqrt{w_o^2 - \frac{b^2}{4m^2}$

$(0.998w_o)^2 = w_o^2 -\frac{b^2}{1}$

$b^2 = w_o^2 -(0.998w_o)^2$

$b^2 = w_o^2(1-0.998^2) = 3.996 *10^{-3} w_o^2$

$b = w_o\sqrt{3.996*10^{-3}}$

$b = \frac{12.5}{0.5}\sqrt{3.996*10^{-3}} = 1.58 kg s^{-1}$

b) $x = x_m e^{\frac{-bt}{2m}}$

$x = x_m e^{-1.58t}{1} = x_m e^{-1.58t}$ where x_m is initial amplitude

c) critical damping amplitude

$c_c =2\sqrt{km} = 2\sqrt{12.5*.5} = 5 kg s^{-1}$

The terrestrial planets are made almost entirely of elements heavier than hydrogen and helium. According to modern science, wher

Hydrogen makes stars and stars spend most of their lifetime making helium.

The heavier elements are made when an old-age, high mass star explodes as a nova or supernova and then dies.

(a) What is the escape speed on a spherical asteroid whose radius is 500. km and whose gravitational acceleration at the surface

navik [9.2K]

Answer:

a) v= 1732.05m/s

b) d=250000m

c) v= 1414.214m/s

Explanation:

Notation

M= mass of the asteroid

m= mass of the particle moving upward

R= radius

v= escape speed

G= Universal constant

h= distance above the the surface

Part a

For this part we can use the principle of conservation of energy. for the begin the initial potential energy for the asteroid would be $U_i =-\frac{GMm}{R}$ .

The initial kinetic energy would be $\frac{1}{2}mv^2$ . The assumption here is that the particle escapes only if is infinetely far from the asteroid. And other assumption required is that the final potential and kinetic energy are both zero. Applying these we have:
