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

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  =  m v²  

Now, insert the parameters and solve;

  K.E  =    x 1 x 12  = 6J

The change in kinetic energy is 6J

the closer the planet is to the sun, the larger the gravity
