Hooke's law describes a certain light spring of unstretched length 34.0 cm. When one end is attached to the top of a door frame, and a 8.60 kg object is hung from the other end, the length of the spring is 42.00 cm (a) Find its spring constant 579 X Your response differs from the correct answer by more than 10%. Double check your calculations. kN/m (b) The load and the spring are taken down. Two people pull in opposite...

A spring hangs from the ceiling with an unstretched length of x,-0.51 m. A mi 9.1 kg block is hung from the spring, causing the spring to stretch to a length x,-0.64 m. Find the length Δx of the spring when a m2 2.5 kg block is hung from the spring. For both cases, all vibrations of the spring are allowed to settle down before any measurements are made.

A spring with unstretched length Lo = 13 cm is hung vertically. You attach a mass m = 50 g to the bottom of the spring and find it now has a total length of 20 cm. You then pull down on the mass stretching it an additional s = 1 cm. (a) Draw and label a diagram, find the (b) position, (c) velocity, and (d) acceleration of the mass at time t-0.1 s. (e) Find the period of oscillation....

2. Determine the unstretched length (length with no force developed) in the spring assuming the box has a mass of 40kg, is in equilibrium and the spring constant (k) is 180 N/m OC 1. A force of 800N is used to pull point A. Determine the tensions in each cable (DA, BA and CA) required to hold point A in equilibrium. DJ - 3 m -3m- 4 m -4mB

The spring in the figure (Figure 1)
(a) is
compressed by length ?x. It launches the block across a
frictionless surface with speed v0. The two springs in
thefigure (Figure 2)
(b) are
identical to the spring of thefigure
(a). They are
compressed by the same length ?x and used to launch the
same block.

A block with mass 0.5 kg is connected by a spring of relaxed length 0.10 m to a post at the center of a low-friction table. You pull the block straight away from the post and release it, and you observe that the period of oscillation is 0.9 s. Next you stretch the spring to a length of 0.22 m and give the block an initial speed v perpendicular to the spring, choosing v so that the motion is a...
