Bubba runs and dives off the edge of a 27.3 m tall cliff at 5.74 m/s into the lake below. how does it take bubba to land in the water

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.

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?

Wind and moving water provide energy. question 1 options: chemical mechanical thermal none of the above
