Use the worked example above to help you solve this problem. A block with mass of 5.19 kg is attached to a horizontal spring with spring constant k = 3.25 x 102 N/m, as shown in the figure. The surface the block rests upon is frictionless. The block is pulled out to x, = 0.0540 m and released. (a) Find the speed of the block at the equilibrium point. V m/s .4273 (b) Find the speed when x = 0.026 m. |4271 Your response differs from the correct answer by more than 10%. Double check your calculations. m/s (c) Repeat part (a) if friction acts on the block, with coefficient u; = 0.160. .312 Your response differs from the correct answer by more than 100%. m/s

any help would be great, thanks in advance

Use the worked example above to help you solve this problem. A block with mass of 5.19 kg is attached to a horizontal spring with spring constant k = 3.25 x 102 N/m, as shown in the figure. The surface the block rests upon is frictionless. The block is pulled out to x, = 0.0540 m and released. (a) Find the speed of the block at the equilibrium point. V m/s .4273 (b) Find the speed when x = 0.026 m. |4271 Your response differs from the correct answer by more than 10%. Double check your calculations. m/s (c) Repeat part (a) if friction acts on the block, with coefficient u; = 0.160. .312 Your response differs from the correct answer by more than 100%. m/s EXERCISE HINTS: GETTING STARTED I'M STUCK! Use the values from PRACTICE IT to help you work this exercise. Suppose the spring system in the last example starts at x = 0 and the attached object is given a kick to the right, so it has an initial speed of 0.67 m/s. (a) What distance from the origin does the object travel before coming to rest, assuming the surface is frictionless? .084 m (b) How does the answer change if the coefficient of kinetic friction is u, = 0.160? (Use the quadratic formula.)
