Ahorse of weight w presses down on the ground with a magnitude f and becomes airborne as a result. the magnitude of the force the ground exerted on the horse must have been equal to w and less than f equal to w and equal to f more than w and equal to f more than w and more than f if anybody can let me know this answer asap, it would be appreciated.

Third option

More than w and equal to F

Explanation:

If the horse presses the floor with a force F, then it follows that by Newton's third law, the floor makes a force -F on the horse.

Then if this force F is greater than the weight w of the horse, then the horse accelerates upwards and rises from the ground.

We know that after pressing the floor with a force F, the horse gets up off the floor. Then it is true that:

The force exerted by the floor on the horse is equal to F and greater than w

The answer is the third option more than w and equal to F

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

explanation:

newton's third law, for every action there is an equal and opposite reaction.
