Question

С какой скоростью двигается тело по окружности радиусом 20 метров, если центростремительное ускорение тела равно 3,2 м/c

Answer 1

V=sqrt(a*R)=sqrt(3,2*20)=8 м/с

Answer 2

Calculating the Speed of an Object Moving in a Circular Path

To calculate the speed of an object moving in a circular path with a given centripetal acceleration, we can use the formula:

V = √(a * R)

Where: - V = speed of the object - a = centripetal acceleration - R = radius of the circular path

Given that the centripetal acceleration a is 3.2 m/s² and the radius R is 20 meters, we can calculate the speed V using the provided formula.

Calculation

Using the formula V = √(a * R): - V = √(3.2 m/s² * 20 m) - V = √(64 m²/s²) - V = 8 m/s

So, the speed of the object moving in a circular path with a radius of 20 meters and a centripetal acceleration of 3.2 m/s² is 8 m/s.
