The kinetic energy of the bowling ball with the mass and traveling at the given velocity is 10.14 Joules.
<h3>
What is Kinetic Energy?</h3>
Kinetic energy is simply a form of energy a particle or object possesses due to its motion.
It is expressed as;
K = (1/2)mv²
Where m is mass of the object and v is its velocity.
Given that;
- Mass of the bowling ball m = 3kg
- Velocity of the bowling ball v = 2.6m/s
We substitute the given values into the above equation.
K = (1/2)mv²
K = 0.5 × 3kg × (2.6m/s)²
K = 0.5 × 3kg × 6.76m²/s²
K = 10.14kgm²/s²
K = 10.14J
Therefore, the kinetic energy of the bowling ball with the mass and traveling at the given velocity is 10.14 Joules.

Answer:
-1458
Step-by-step explanation:
Let's find the rule of the sequence. It seems that each term is -3 times the previous term.
Let's continue the sequence.
486, -1458
-1458 is the 7th term
