Question

Верхнюю точку моста радиусом 100 м автомобиль проходит со скоростью 20 м/с. Найдите центростремительное ускорение автомобиля.

Answer 1

A=v²/R  a=20²/100=400/100=4

Answer 2

A=V^2/R=400/100=4м/c^2

Answer 3

Calculation of Centripetal Acceleration

To find the centripetal acceleration of a car passing through the top point of a bridge with a radius of 100 m and a speed of 20 m/s, we can use the formula for centripetal acceleration:

Centripetal acceleration (a) = (v^2) / r

Where: - v is the velocity of the car - r is the radius of the circular path

Substituting the given values into the formula, we have:

Centripetal acceleration (a) = (20^2) / 100

Calculating the expression, we get:

Centripetal acceleration (a) = 400 / 100 = 4 m/s^2.

Therefore, the centripetal acceleration of the car is 4 m/s^2.
