1 point Suppose a spring with spring constant 1 Nm is horizo

(1 point) Suppose a spring with spring constant 1 N/m is horizontal and has one end attached to a wall and the other end attached to a mass. You want to use the spring to weigh items. You put the spring into motion and find the frequency to be 1.4 Hz (cycles per second). What is the mass? Assume there is no friction.

Solution

2(phi)N=(k/m)^1/2

where phi=22/7

where k=1

N=1,4

so 1/m=(2(22/7)(1,4))^2

so m=,012913
