Question

Груз какого веса можно поднять на высоту 5 м совершив работу 20 дж?

Answer 1

Дано h=5 м    A=20 Дж       P- ?

A=m*g*h=P*h

P=A/h=20/5=4 Н

Answer 2

Работа - A=Fs
F=A/s=20/5=4 Н                            

Answer 3

Calculating Work Done to Lift an Object to a Certain Height

To calculate the work done to lift an object to a certain height, we can use the formula:

Work (W) = Force (F) × Distance (d)

Where: - Force (F) is the force required to lift the object. - Distance (d) is the height to which the object is lifted.

In this case, the work done is given as 20 J and the height is 5 m. We can use this information to calculate the force required to lift the object.

Calculating the Force Required

Using the formula for work, we can rearrange it to solve for force:

Force (F) = Work (W) / Distance (d)

Substituting the given values: F = 20 J / 5 m = 4 N

So, the force required to lift the object to a height of 5 m is 4 N.

Conclusion

To lift an object to a height of 5 m while performing 20 J of work, a force of 4 N is required.
