A particle starts S.H.M from the mean position. Its amplitude is A and time period is T. At the time its speed is half of the maximum speed. Its displacement y from the mean position is:
Two springs of constants k1 and k2 have equal maximum velocities when executing simple harmonic motion. The ratio of their amplitudes (the masses are equal) will be:
A wave has SHM (simple harmonic motion) whose period is 4 s while another wave which also possesses SHM has its period 3 s. If both are combined, then the resultant wave will have the period equal to:
4 s
5 s
12 s
3 s
A mass of 2.0 kg is put on a flat pan attached to a vertical spring fixed on the ground as shown in the figure. The mass of the spring and the pan is negligible. When pressed slightly and released the mass executes a simple harmonic motion. The spring constant is 200 N/m. What should be the minimum amplitude of the motion, so that the mass gets detached from the pan ?(Take g =10m/s2 )
8.0 cm
10.0 cm
Any value less than 12.0 cm
4.0 cm
A system exhibiting S.H.M. must possess:
