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
Correct answer is C
From two parts 20m apart
a = 10m, x = 6m, A = 5
V = ω√A2−X2 = 5√102−62 = 40m/s
