Question

С какой скоростью движется автомобиль по закруглению радиусом 20 м, если его центростремительное ускорение равно 5 м/с^ 2? Помогите пожалуйста!!!!

Answer 1

A=u(2)/r=>u=√a/r=√25/20=1,1м/c

Answer 2

Calculating the Speed of a Car on a Curve

To calculate the speed of a car moving along a curve with a radius of 20 m and a centripetal acceleration of 5 m/s^2, we can use the formula for centripetal acceleration:

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

Where: - a = centripetal acceleration - v = velocity - r = radius of the curve

We can rearrange this formula to solve for velocity:

v = √(a * r)

Calculating the Velocity

Substituting the given values: - a = 5 m/s^2 - r = 20 m

We can calculate the velocity using the formula:

v = √(5 * 20) v = √100 v = 10 m/s

So, the speed of the car on the curve with a radius of 20 m and a centripetal acceleration of 5 m/s^2 is 10 m/s.
