Calculate the average speed (in m/s) of a cheetah that runs 140 meters in 5 seconds

Answers

should be 28 meters per second.
140m ÷ 5s

Final answer:

The average speed of a cheetah that runs 140 meters in 5 seconds is calculated by dividing the distance by time, which equals 28 m/s.

Explanation:

To calculate the average speed of a cheetah running a distance of 140 meters in 5 seconds, we use the formula for average speed which is:

Average Speed = Distance / Time

Substituting the given values of distance and time in this equation, we get:

Average Speed = 140 meters / 5 seconds

Solving this, we obtain the average speed of the cheetah as 28 m/s.

The average speed is a scalar, meaning we do not include direction in the answer. For comparison purposes, the speed of a typical automobile might be around 15 m/s.

How can you calculate distance when given power, time, and mass?Power used to lift crate is 3490, mass of crate is 425 kg, time is 3 seconds. How far was the crate lifted?

Answers

First step:   Power = (work done) / (time to do the work).

   3490 watts = (work done) / (3 seconds)

   3490 joules/second = (work done) / (3 seconds)

Multiply each side by 3 seconds:

   Work done = (3490 x 3) joules = 10,470 joules

Second step:    Weight = (mass) x (gravity)

   Weight of the crate = (425 kg) x (9.8 m/s²)

= 4165 newtons

Step 3: Work done = (force) x (distance)

   = (weight) x (distance lifted)

10,470 joules = (4165 newtons) x (distance)

Divide each side by 4165 newtons:

   Distance = 10,470 kg-m²/sec² / 4165 kg-m/s²

   =    2.514... meters (rounded)

You asked: "How can you calculate ... ?"
Notice that I did the same thing in all 3 steps ... write down the formula
for finding a quantity, then write the numbers you know into the formula
to find the quantity.

THAT's "how", and it all boils down to knowing the formulas and picking
the right one to work with. The right one to pick is the one that talks about
all (or most) of the quantities that you know AND the quantity that you're
trying to find.

For example, if you need to find how long it will take your turtle to walk
across the room, then you need a formula that talks about time, speed,
and distance. You would not get much help from the formula that talks
about the pressure and volume of a gas, or one that talks about the
frequency and wavelength of light waves, or Einstein's formula E=mc²
for the equivalency of mass and energy.

A 10.0 kilogram mass of iron on earth exerts a downward force of 98 Newtons. On the moon this same 10.0 kilograms of iron is weighed and found to exert a downward force 16.3 Newtons. How is this possible ?

Answers

The weight of an object is the force it experience by the gravitational pull of the planet. The gravitational pull by earth is greater than that from moon. This leads to greater weight in earth than in moon.

What is gravitational force ?

Gravitational force is a kind of force by which an object attracts other objects into its center of mass. The force exerted between the objects depends on the mass and distance between them.

Earth exerts a gravitational pull to every objects on its surface and that's why we are standing on the ground. We experience a weight downwards due to this force.

The acceleration due to gravity in earth = 9.8 m/s²

g in moon = 1.63m/s².

then weight = m g

the weight of a 10 kg iron bar in earth is 98 N and that in moon will be 16.3 N.

Answer:

The decrease in the downward force that a mass of iron can exert on the moon versus the force it exerts on earth is due to:

The force of gravity on Earth is greater than the force of gravity on the moon.

Explanation:

To recognize the calculation within the statement, you must know that the Newton unit is equal to:

Newton = (Kilogram * meter) / second ^ 2

And that the gravities of the Earth and the Moon are:

Earth gravity = 9.807 m / s ^ 2
Moon gravity = 1.63 m / s ^ 2

Finally, you must know the force formula (since we are talking about a descending force):

Force = mass * acceleration (gravity is a measure of acceleration)

Since the mass in both cases is the same (10 kilograms), the variation in acceleration will provide different values of descending force, as shown below, replacing the values:

Downward force on Earth = 10 Kg * 9,807 m / s ^ 2 = 98.07 Kg * m / s ^ 2 = 98.07 Newtons.
Downward force on the Moon = 10 Kg * 1.63 m / s ^ 2 = 16.3 Kg * m / s ^ 2 = 16.3 Newtons.

As you can see, when it comes to force, the less acceleration (in this case less gravity), the lower the downward force will be with a mass of equal weight.
