5. A runner of mass 60 kg accelerates at 2.0 m/s2 at the start of a
race. Calculate the force provided from her legs.​

Answers

Answer:

F = 120 N

Explanation:

Given that,

The mass of a runner, m = 60 kg

Acceleration of the runner, a = 2 m/s²

We need to find the force provided from her legs. The formula for force is given by :

F = ma

Substitute all the values,

F = 60 kg × 2 m/s²

= 120 N

So, the required force is equal to 120 N.

The provided force will be "120 N".

Given:

Mass,

m = 60 kg

Acceleration,

a = 2.0 m/s²

As we know that,

→ [tex]Force = Mass\times Acceleration[/tex]

or,

→ [tex]F = ma[/tex]

then,

      [tex]= 60\times 2.0[/tex]

      [tex]= 120\ N[/tex]

Thus the above answer is right.

At which position is the LOWEST potential energy?

Answers

The answer is position 3, because it is at its lowest point.

Potential Energy is “stored energy.” It is energy that is ready to be converted or released as another type of energy. We most often think of potential energy as gravitational potential energy. When objects are higher up, they are ready to fall back down. When you stretch an object and it has a tendency to return to its original shape, it is said to have elastic potential energy. Chemical potential energy is the stored energy in a substance’s chemical structure that can be released in a chemical reaction or as heat.

How do you calculate the average velocity of mercury as it orbits the sun?

Answers

Answer:Hope this helps!!!!!

Explanation:

People are fascinated with high-speed travel. A Boeing 747 flies at about 550 miles per hour. The Concorde Supersonic Transport flew over twice as fast at about 1350 miles per hour. That is impressively fast, but consider the speeds that we passengers on planet Earth always travel. The circumference of the Earth at the equator is 24900 miles and the residents of the tropic areas travel that distance every 24 hours. They are traveling over a thousand miles an hour. At 38° latitude we are traveling about 820 miles per hour. That is quite impressive but it pales in comparison with the orbital speed of the Earth, The average distance of the Earth from sun is 93.5 million miles. This means that in 365.25 days the Earth travels 587.5 million miles. This works out to about 67 thousand miles per hour. This is the speed we travel 24 hours a day, 365.25 days a year.

The orbital velocity is 2πR/T where R is the average radius of the orbit and T is the length of the year. The orbital velocity of a planet relative to that of Earth's is then the relative radius divided by the relative length of the year.

A skydiver of mass mmm jumps from a hot air balloon and falls a distance ddd before reaching a terminal velocity of magnitude vvv. Assume that the magnitude of the acceleration due to gravity is g.

Required:
Find the power Pd supplied by the drag force after the skydiver has reached terminal velocity v. (in same terms)

Answers

Answer:

Explanation:

When the object falling attains terminal velocity , net force on it becomes zero. That means drag force becomes equal and opposite to its weight.

So drag force = mg

where m is mass of falling body and g is acceleration due to gravity .

The drag force is constant . It is doing work against the weight of falling body . Object is falling v m /s . That means drag force is doing work per second as follows

Work done per second = force x displacement per second

= mg x v

So

Power of drag force = mgv.

Pd = mgv.

A body of mass 11 kg is subjected to a net force of 20 N East for 30 s. Calculate the change in
velocity of the body.

Answers

Answer:

54.55 m/s

Explanation:

From the question above,

Change in velocity = impulse/mass

Δv = I/m = Ft/m................... Equation 1

Where F = force, t = time, m = mass

Given: F = 20 N, t = 30 s, m = 11 kg

Substitute these values into equation 1

Δv = (20×30)/11

Δv = 600/11

Δv = 54.55 m/s

Hence the change in velocity of the body is 54.55 m/s

The change in velocity of the body is 54.54 m/s

The velocity of the body of an object is the change of the distance of the object with time.

From the information given:

the mass of the b0dy = 11 kg

the net force F = 20 N

the time (t) = 20 s

Similarly;

Force = ma

20 = 11 ×  (a)

[tex]\mathbf{a = \dfrac{20}{11} \ m/s^2}[/tex]

a = 1.818 m/s²

However, the acceleration of an object is the change in velocity with time.

[tex]\mathbf{a = \dfrac{\Delta V}{t}}[/tex]

ΔV =  (a) ×  (t)

ΔV = 1.818 m/s² × 30 s

ΔV = 54.54 m/s

The equation for centripetal force can be derived by substituting the equation for centripetal acceleration into Newton’s second law.


Please select the best answer from the choices provided

T
F

Answers

Answer:

True.

Explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

[tex] F = ma[/tex]

Centripetal acceleration is given by the formula;

[tex] Acceleration, a = \frac {v^{2}}{r}[/tex]

Where;

v is the velocity.

r is the radius.

The equation for centripetal force can be derived by substituting the equation for centripetal acceleration into Newton’s second law.

Let centripetal force be Fc

Fc = ma

Substituting the value of "a" into the above formula;

[tex] Fc = m \frac {v^{2}}{r} [/tex]

[tex] Fc = \frac {mv^{2}}{r} [/tex]

What is fossil?

A fossil is an item that has survived in the Earth's crust as a remnant, impression, or trace of an extinct animal or plant. The main repository for knowledge regarding the evolution of life on Earth is the complex of information preserved in fossils found all across the world.

Fossils of dinosaurs discovered in Alberta, Canada. Only a small percentage of extinct species have been preserved as fossils, and often only those with a sturdy skeleton are capable of doing so. A calcareous skeleton or shell is present in the majority of major groups of invertebrate creatures (e.g., corals, mollusks, brachiopods, bryozoans). Other types have silicon dioxide or calcium phosphate shells (both of which are found in the bones of vertebrates).
