$v=2\ m/s\\\\E_k=16\ J=16\ \frac{kgm^2}{s^2}\\\\E_k=\frac{mv^2}{2}\\\\\frac{m\cdot(2\ m/s)^2}{2}=16\ \frac{kgm^2}{s^2}\\\\\frac{m\cdot4\ m^2/s^2}{2}=16\ \frac{kgm^2}{s^2}\\\\2m\ m^2/s^2=16\ \frac{kgm^2}{s^2}\ \ /:2\ m^2/s^2\\\\m=8\ kg-answer$

<h3>What is arithmatic progression?</h3>

The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmatic progression

Here we have the data:-

The bottom row has 61 cups

If there are 16 total rows

The number of the cups will be calculated as:-

$S_n=\dfrac{n(a_1+a_n)}{2}$
