A mass of 0.4 kg, hanging from a spring with a spring constant of 80 N/m, is set into an up-and-down simple harmonic motion. What is the velocity of the mass when at its maximum displacement of 0.1 m?

Answers

Answered by Matthew
its maximum displacement is also its Amplitude. When an object is in SHM and reaches its A, its velocity is zero.

1.4 m/s

Total E=1/2KA^2
Kinetic E=1/2mv^2

Kinetic E= Total E

1/2(80)(0.1)^2=1/2(0.40)(v)^2
v=1.4 m/s

Answer is 0 m/s. At maximum displacement there is no velocity
