Question

A light block hangs at rest from the end of a spring when it is pulled down 10 cm and released. Assume the block oscillates with an amplitude of 10 cm on either side of its initial position, and with a period of 6 s. Find a function d(t) that gives the displacement of the block t seconds after it is released, where d(t)> 0 represents downward displacement. Rest position, d0 dl)>0. d(t)cos (Simplify your answers. Type exact answers, using ? as needed. Use angle measures greater than or equal to 0 and less than 2

Explanation / Answer

amplitude = 10

period = 6s

2pi/b = 6

b = pi/3

hence,

d(t) = 10 cos (pi/3) t
