Consider the mass-pulley-spring system shown below:
a) What are the values of"x'' and "h" when the system is in equilibrium?
b) M is lifted to a height of 1 m and then dropped. Find its speed as it passes through the equilibrium point.
c) As M oscillates (vibrates) about the EQ position find the maximum value of x.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
