Moderate

A body moves on a circular path subtending an angle of 2 radians at the center of a circle of radius 3.5 meters. The linear displacement of the body is _.

Correct answer: B. 7.0 m

  • A. 6.5 m
  • B. 7.0 m
  • C. 7.5 m
  • D. 1.75 m

Explanation

The formula to be used here:S=rθ {where S is the arc length or the linear displacement, r is the radius and θ is the angle in radians}S= (3.5)(2)∵ S= 7.0m

About Angular and Linear Quantities

Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
