Question

Find the change in kinetic energy of a 1.0 kg fish leaping to the right at 12.0 m/s.

Answer 1

Hey yall, the answer is 72 J.

Step-by-step explanation:

Answer 2

6J

Step-by-step explanation:

Given parameters:

Mass of fish = 1kg

Velocity = 12m/s

Unknown:

Change in kinetic energy = ?

Solution:

Kinetic energy is the energy due to the motion of a body. It is mathematically given as:

K.E =
`(1)/(2)` m v²

Now, insert the parameters and solve;

K.E =
`(1)/(2)` x 1 x 12 = 6J

The change in kinetic energy is 6J
