Two identical massless springs are hung from a horizontal support. A block of mass 4.3 kg is suspended from the pair of springs, as shown. The acceleration of gravity is 9.8 m/s. 0000 4.3 kg When the block is in equilibrium, each spring is stretched an additional 0.16 m. The force constant of each spring is most nearly

(b) (3 points) A ball of mass m is attached to a spring (with unstretched length lo and spring constant k) which hangs vertically. The ball is initially held at rest with the spring at its unstretched length. Then, the ball is let go. Consider the instant when the ball reaches its lowest position (the spring stretches to its maximum length and s instantaneously at rest), I was done by the spring force during this process (that is from release...

Review Part A You have a lightweight spring whose unstretched length is 4.0 cm. First, you attach one end of the spring to the ceiling and hang a 1.6 g mass from it. This stretches the spring to a length of 5.3 cm. You then attach two small plastic beads to the opposite ends of the spring, lay the spring on a frictionless table, and give each plastic bead the same charge. This stretches the spring to a length of...

II Review Part A You have a lightweight spring whose unstretched length is 4.0 cm. First, you attach one end of the spring to the ceiling and hang a 2.6 g mass from it. This stretches the spring to a length of 5.4 cm. You then attach two small plastic beads to the opposite ends of the spring, lay the spring on a frictionless table, and give each plastic bead the same charge. This stretches the spring to a length...

You have a lightweight spring whose unstretched length is 4.0 cm. First, you attach one end of the spring to the ceiling and hang a 3.0 g mass from it. This stretches the spring to a length of 5.0 cm . You then attach two small plastic beads to the opposite ends of the spring, lay the spring on a frictionless table, and give each plastic bead the same charge. This stretches the spring to a length of 4.6 cm...

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....

As shown, a frictionless pulley hangs from a system of
springs and a cable. The pulley is equidistant between the two
supports attaching the springs to the ceiling. The distance between
the supports is d=1.50 m . The cable cannot stretch and its length
between the two springs is 1.8 m.

Review Part A You have a lightweight spring whose unstretched length What is the magnitude of the charge (in nC) on each bead? Express your answer using two significant figures is 4.0 cm. First, you attach one end of the spring to the ceiling and hang a 2.4 g mass from it. This stretches the spring to a length of 5.3 cm. You then attach two small plastic beads to the opposite ends of the spring, lay the spring on...
