What is the speed u of the object at the height of (1/2)hmax? Express your answer in terms of v and g. Use three significant figures in the numeric coefficient.

The speed u of the object at the height of (1/2)hmax is 0.707.

At a height that is half of the maximum height the object will have only half of its initial kinetic energy the rest half is converted to potential energy at this point. so

So, The speed u of the object at the height of (1/2) hmax is 0.707.

The speed u of the object at the height of (1/2) hmax is .

Explanation:

At a height that is half of the maximum height, the object will have only half of its initial kinetic energy, the rest half is converted to potential energy at this point. So,

                                  .

The speed u of the object at the height of (1/2) hmax is .

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.
