Question

A body is executing shm which is given by y=8cos (50t+2π)cm what is amplitude,displacent , frequency , acceleration

Answer 1

Answer:

Amplitude= 8

acceleration=20,000

frequency=25/π

here omega=50

and omega=2π/T

therefore we get T=π/25

but frequency=1/T

therefore we get f=25/π

acceleration= -amplitude×omega^2

therefore we get a=-20000

remember here negative sign is just to indicate that it is in opposite side to the motion
