Assessment: WAEC SSCE - Physics - 1995 (Objective) Subject: Physics

Question 1 Report

The angular speed of an object describing a circle of radius 4m with a linear constant speed of 10 ms^-1 is

40.00 rad s^-1

14.00 rad s^-1

2.50 rad s^-1

1.58 rad s^-1

0.40 rad s^-1

Answer Details

The linear speed v and the angular speed ω of an object describing a circle of radius r are related by the equation: v = rω Rearranging the equation to solve for ω, we have: ω = v/r Substituting the given values, we get: ω = 10 ms^-1 / 4m = 2.50 rad s^-1 Therefore, the angular speed of the object is 2.50 rad s^-1. Answer: (c) 2.50 rad s^-1.
