step 3: calculate the pre... calculate the change in the kinetic energy (k... bottle when the mass is increased. use the fo... ( ke = \frac{1}{2}mv^2 ), where m is the mass and v is th... (velocity). assume that the speed of the soda... falling from a height of 0.8 m will be 4 m/s, and use this speed for ea... calculation. record your calculations in table a of your student guide. ... when the mass of the bottle is 0.500 kg, the ke is dropdown with 2,4,5,8 kg • m²/s².

Explanation:

Step1: Identify the formula and values

We use the kinetic energy formula \( KE = \frac{1}{2}mv^2 \), where \( m = 0.500 \, \text{kg} \) and \( v = 4 \, \text{m/s} \).

Step2: Substitute the values into the formula

First, calculate \( v^2 \): \( v^2 = (4)^2 = 16 \, \text{m}^2/\text{s}^2 \). Then, substitute \( m \) and \( v^2 \) into the formula: \( KE=\frac{1}{2}\times0.500\times16 \).

Step3: Perform the calculation

\( \frac{1}{2}\times0.500 = 0.250 \), then \( 0.250\times16 = 4 \).
