Question

Равномерно поднимая груз на высоту 0,5 м, спортсмен совершает работу 160дж.Какая сила тяжести действует на груз? А.320Н Б.160Н В.80Н Г.800Н Д.8Н

Answer 1

A=FS
F=A/S
F=160/0,5=320Н
на груз действует сила тяжести 320 Н

Answer 2

Calculating the Force Acting on the Load

To calculate the force acting on the load, we can use the formula:

Work (W) = Force (F) × Distance (d)

Given that the work done is 160 J and the distance is 0.5 m, we can rearrange the formula to solve for force:

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

Substituting the given values:

Force (F) = 160 J / 0.5 m

Calculating the force:

Force (F) = 320 N

So, the force acting on the load is 320 N (Option A).
