Final answer:
The kinetic energy of Finn and Jake, who have a combined mass of 130 kg and a velocity of 12 m/s, is calculated using the formula KE = 0.5 × mass × velocity^2, resulting in a kinetic energy of 9360 Joules.
Step-by-step explanation:
The question pertains to calculating the kinetic energy of Finn and Jake, who have a combined mass and are moving at a certain velocity. The formula to calculate kinetic energy (KE) is KE = 0.5 × mass × velocity2. Given that their combined mass is 130 kg and they have a velocity of 12 m/s, their kinetic energy can be calculated as follows:
KE = 0.5 × 130 kg × (12 m/s)2 = 0.5 × 130 × 144
= 0.5 × 18720
= 9360 Joules
Therefore, Finn and Jake have a kinetic energy of 9360 Joules.
