Question

A frictionless block of mass 1.55 kgkg is attached to an ideal spring with force constant 350 N/m . At t=0 the spring is neither stretched nor compressed and the block is moving in the negative direction at a speed of 12.9 m/s .

a)Find the amplitude.

b)Find the phase angle.

c)Write an equation for the position as a function of time.

a)x=(−x=(−0.858 mm )sin(()sin((15.0 rad/srad/s )t))t)

b)x=(−x=(−0.858 mm )cos(()cos((15.0 rad/srad/s )t))t)

c)x=(−x=(−15.0m)sin((m)sin((0.858rad/s)t)rad/s)t)

d)x=(−x=(−15.0m)cos((m)cos((0.858rad/s)t)rad/s)t)
