Question 1 Report

An object moves in a circular path of radius 0.5m with a speed of 1ms-1 What is its angular velocity?

8 rads-1

4 rads-1

2 rads-1

1 rads-1

Answer Details

The angular velocity of an object moving in a circular path is the rate at which the object is rotating around the center of the circle. It is usually measured in radians per second (rad/s). To find the angular velocity of the object in this question, we can use the formula: angular velocity = speed / radius where speed is the speed of the object and radius is the radius of the circular path. Substituting the values given in the question, we get: angular velocity = 1 m/s / 0.5 m which simplifies to: angular velocity = 2 rad/s Therefore, the answer is 2 rads-1.
