A body moves in SHM between two point 20m on the straight line Joining the points. If the angular speed of the body is 5 rad/s. Calculate its speed when it is 6m from the center of the motion.
- 20 m/s
- 30 m/s
-
40 m/s
- 50 m/s
The correct answer is: C
Explanation
From two parts 20m apart
a = 10m, x = 6m, A = 5
V = ω\(\sqrt{A^2 - X^2}\) = 5\(\sqrt{10^2 - 6^2}\) = 40m/s
