Question

step 6: calculate the pred of the falling soda bottles in this part of the experiment, you will be chan speed of the bottle by dropping it from differen you will use the same mass, 0.250 kg, for eac record this mass in table b for each velocity. calculate the expected kinetic energy (ke) at velocity. use the formula ( ke = \frac{1}{2}mv^2 ), where m is the mass and v is the speed. record your bottle is 2 m/s, the ke is bottle is 3 m/s, the ke is when the speed of the bottle is 4 m/s, the ke is kg • m²/s².

Explanation:

Step1: Identify given values

Mass \( m = 0.250 \, \text{kg} \), velocity \( v = 4 \, \text{m/s} \), kinetic energy formula \( KE=\frac{1}{2}mv^{2} \).

Step2: Substitute values into formula

Substitute \( m = 0.250 \) and \( v = 4 \) into \( KE=\frac{1}{2}mv^{2} \).
\( KE=\frac{1}{2}\times0.250\times(4)^{2} \)

Step3: Calculate step by step

First, calculate \( (4)^{2}=16 \).
Then, \( \frac{1}{2}\times0.250 = 0.125 \).
Finally, \( 0.125\times16 = 2 \).

Answer:

\( 2 \)
