A body executing S, H, M along a straight line has a velocity of 3 ms⁻¹ when it is a distance of 4 m from its mean position and 4 ms⁻¹ when it is at a distance of 3 m from its mean position. Its angular frequency and amplitude are:
a. 2 rad s⁻¹ & 5 m
b. 1 rad s⁻¹ & 10 m
c. 2 rad s⁻¹ & 10 m
d. 1 rad s⁻¹ & 5 m
