The body moves in a circle with a radius of 5m. centripetal acceleration is 20m / s2. find the linear velocity.
| June 19, 2021 | education
To calculate the linear speed with which a given body should move in a circle, we use the formula: ac = V ^ 2 / R, from where we express: V = √ (ac * R).
Values of variables: ac – centripetal acceleration of the body (ac = 20 m / s2); R is the radius of the circle (R = 5 m).
Calculation: V = √ (ac * R) = √ (20 * 5) = 10 m / s.
Answer: A given body moves in a circle with a linear speed of 10 m / s.
