How high could one horse raise a 100N weight (10kg) in 1 second?

7.46m

To determine how high a horse could raise a 100N weight in 1 second, we need to apply the laws of physics.

First, let's start by calculating the work done by the horse on the weight. Work is defined as the force applied over a certain distance, which can be calculated using the formula:

Work = Force × Distance

In this case, the force applied by the horse is the weight of the object, which is 100N, and the distance it needs to raise the weight is what we want to find.

Next, we can use the equation for work to solve for the distance:

Distance = Work / Force

Since the work done by the horse is the same as the potential energy gained by lifting the weight, we can also write:

Potential Energy = m × g × h

where m is the mass (10kg), g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height lifted.

Rearranging this equation, we can solve for the height:

h = Potential Energy / (m × g)

Now we can substitute the values:

h = (100N) / (10kg × 9.8 m/s²)

Simplifying the equation:

h = 1 / (0.98 m/s²)

Therefore, the horse could raise the 100N weight approximately 1.02 meters high in 1 second.
