Question

Как известно,Карлсон который живёт на крыше,перемещается по воздуху при помощи пропеллера.Мощность пропеллера довольно велика-он может подня не только Карлсона,но и фрекен Бок вместе с креслом.Постарайтесь определить приблизительно,какова мощность пропеллера(сколько килограммов он способен поднять) ,прикикинув массы Карлсона,фрекен Бок и кресла,в котором она сидит.

Answer 1

9кг(кресло)+78кг(Фрекен бок)+42кгкарлосон=129кг

Answer 2

Calculating the Power of the Propeller for Karlsson and Freken Bok

To estimate the power of the propeller required to lift Karlsson and Freken Bok along with the chair, we can calculate the total weight of the three individuals and the chair. Then, we can use this total weight to estimate the power needed to lift them.

Step 1: Calculate the Total Weight

Let's consider the approximate weights of Karlsson, Freken Bok, and the chair. According to the provided information, Karlsson is a relatively small and light person, while Freken Bok is an average-sized woman. The chair's weight should also be factored in.

Step 2: Estimate the Power

Once we have the total weight, we can estimate the power required to lift them. This can be done by considering the force of gravity acting on the total weight and the speed at which they need to be lifted.

Conclusion

Based on the estimated total weight of Karlsson, Freken Bok, and the chair, we can calculate the power required for the propeller to lift them. This estimation will provide an approximate idea of the power needed for such a scenario.
