Answer:

a) 16.45 \frac{m}{s} b) 36.94 \frac{mi}{h}

Explanation:

The average speed is given by the formula: \frac{distance}{time}

The distance covered is 2011.25m , and the time is 122.2s.

Replacing in the formula: speed_{avg} = \frac{2011.25 m}{122.2s}

Resulting in a) speed_{avg} = 16.45 \frac{m}{s}.

To get the result in mi/h, do the following conversion:

<em>Knowing : 1 mi = 1603 m   and  1 h = 3600 seg </em>

  • <em> 16.45\frac{ m}{s}*(\frac{1mi}{1603m } ) *(\frac{3600s}{1h} ) = 36.94\frac{mi}{h}</em>

Marianna [84]

Answer:

972 J

Explanation:

At the bottom, all the gravitational potential energy was converted into kinetic energy. If you calculate the GPE, its value will be the same that the KE at the bottom. The GPE can be calculated this way:

GPE = mass×gravity×heigth

GPE = 2.2×9.8×45.08 ≈ 972
