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.
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.

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.
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:
Explanation:
To recognize the calculation within the statement, you must know that the Newton unit is equal to:
And that the gravities of the Earth and the Moon are:
Finally, you must know the force formula (since we are talking about a descending force):
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:
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.
