Web15 sep. 2024 · Example 4.15. An object travels a distance of 35 ft in 2.7 seconds as it moves along a circle of radius 2 ft. Find its linear and angular speed over that time period. Solution: Here we have t = 2.7 sec, r = 2 ft, and s = 35 ft. So the linear speed ν is. ν = s t = 35 feet 2.7 sec ⇒ ν = 12.96 ft/sec , Web7 apr. 2024 · 1 radian is approximately 57.2958°. Consider a half-circle which has radians, which equals to 180°. Hence, 1 radian = \ [ \frac {180^ {0}} {\pi} \] = 57.2958° If you want to convert a degree or an angle to radians, simply multiply the angle by and then divide it by 180.
