Question

автомобиль массой М = 5 т проходит по выпуклому мосту со скоростью 10 м/с. С какой силой он давит на середину моста, если радиус кривизны моста 50м. Земля притягивает автомобиль с силой 50kH

Answer 1

Calculation of the Force Exerted on the Middle of the Bridge

To calculate the force exerted on the middle of the bridge by the car, we can use the centripetal force formula:

F = (m * v^2) / r

Where: - F is the force exerted on the middle of the bridge - m is the mass of the car (given as 5 tons, which is equivalent to 5000 kg) - v is the velocity of the car (given as 10 m/s) - r is the radius of curvature of the bridge (given as 50 m)

Let's substitute the given values into the formula and calculate the force:

F = (5000 kg * (10 m/s)^2) / 50 m

Calculating this expression gives us:

F = 10000 N

Therefore, the car exerts a force of 10000 Newtons on the middle of the bridge.

Please note that the force exerted by the Earth on the car (50 kN) is not relevant to the calculation of the force on the middle of the bridge.
