A0.20 kg particle moves along the x axis under the influence of a stationary object. the potential energy is given by u(x) = 8x2 + 2x4, where u is in joules and x is in meters. if the particle has a speed of 5.0 m/s when it is at x = 1.0 m, its speed when it is at the origin is:

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.

Ineed ! using proper grammar, spelling, and punctuation, write at least one 5 sentence paragraph describing 3 ways we use the elements of the electromagnetic spectrum (ems) in our everyday lives.
