Question

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

Answer 1

Answer:

Hey yall, the answer is 72 J.

Explanation:

Answer 2

Answer:

6J

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  = $\frac{1}{2}$  m v²  

Now, insert the parameters and solve;

  K.E  =  $\frac{1}{2}$  x 1 x 12  = 6J

The change in kinetic energy is 6J
