A mass of 0.3 kg hangs motionless from a vertical spring whose length is 0.75 m and whose unstretched length is 0.55 m. Next the mass is pulle the spring has a length of 1.05 m and given an initial speed upwards of 1.7 m/s. What is the maximum length of the spring during the motion tha maximum length= Hint: the conceptually-simplest approach is to track the changes in kinetic, spring-potential, and gravitational-potential energies; the mathematica approach is to observe that the sole effect of gravitation is to lower the spring's equilibrium position, then track lust the kinetic and spring-potenta

Can someone help me with this question please A 1.38 kg block is shot horizontally from a spring, and travels 0.468 m up a long a frictionless ramp before coming to rest and sliding back down. If the ramp makes an angle of 45.0° with respect to the horizontal, and the spring originally was compressed by 0.14 m, find the spring constant.

As shown in the figure below, a box of mass m = 9.60 kg is slidine across a horizontal frictionless surface with an initial speed v, = 3.40 m/s when k = 2950 N/m. encounters a spring of constant The box comes momentarily to rest after compressing the spring some amount x Determine the final compression x (in m) of the spring. 0.2 Can you write an expression for the initial kinetic energy of the box in terms of its mass and initial speed? What is the final kinetic energy of the box? How is the change in kinetic energy related to the initial and final kinetic energy? Since only conservative forces are acting on the system (box and spring) is energy conserved? How is the change in spring potential energy related to the change in kinetic energy of the box? How is the compression of the spring related to the change in potential energy of the spring and the spring constant? m

A block attached to an ideal spring oscillates without friction on a horizontal table. A student makes the following measurements on the block: •k =77.21 • m =7.88 • A= 1.27 • Vmax- 3.84 • Vave= 0.78 What is the maximum potential energy of the mass-spring system? Round off your final answer to two decimal places.
