Question

Машина равномерно движется со скоростью 20 м/с. определить какую работу совершит двигатель за 10 секунд, если сила тяги его 2000 Н.

Answer 1

A=F*S(расстояние)
S=Vt
A=FVt=400000(Дж)

Answer 2

Calculation of Work Done by the Engine

To determine the work done by the engine, we can use the formula:

Work = Force x Distance

In this case, the force exerted by the engine is given as 2000 N, and we need to find the distance traveled in 10 seconds.

To find the distance, we can use the formula:

Distance = Speed x Time

Given that the speed of the car is 20 m/s and the time is 10 seconds, we can calculate the distance as follows:

Distance = 20 m/s x 10 s = 200 m

Now, we can calculate the work done by the engine:

Work = Force x Distance = 2000 N x 200 m = 400,000 J

Therefore, the engine will perform 400,000 Joules of work in 10 seconds
