A spring with a spring constant of 112 N/m has a mass hung on it so that it stretches 1.2 cm.  Calculate how much mass the spring is supporting.

You have a spring witk k+388 N/m When no extrenal forceis applied on it, the length of the spring is 4.5 cm When you exert F+ 8.5 N of force to stretch this spring,what is the length of the stretched spring in the unit of cm?

A 0.510 kg mass hung from a spring stretches it 0.220 m. II (a) (a) How much (in m) does it stretch two such identical springs if they are hung in parallel, as in (a) of the figure above? (c) How much (in m) does it stretch the two springs if they are hung in series, as in (b) of the figure above? (c) Calculate the effective force (in N/m) constant of a single replacement spring in each case. |N/m (left hand setup) |N/m (right hand setup)

hass weighing 20 pounds stretches a spring 6 inches. The mass is initially released from rest from a point 9 inches below the equilibrium position. (a) Find the position x of the mass at the timest= 1/12, 1/8, 1/6, 11/4, and 91/32 s. (Use g = 32 ft/s? for the acceleration due to gravity.) x(n/12) = ft x(n/8) = ft x(п/6) — ft x(п/4) — ft x(9n/32) ft (b) What is the velocity of the mass when t = 3t/16 s? ft/s In which direction is the mass heading at this instant? O downward O upward (c) At what times does the mass pass through the equilibrium position? п 3D 0, 1, 2, ..

What is the magnitude of the force required to extend the same spring by 80 mm? (in units of N)
