Answer:

Kinetic energy, E = 0.78 Joules

Step-by-step explanation:

Given that,

Mass of frog, m = 0.25 kg

Speed of frog, v = 2.5 m/s

We need to find the kinetic energy of the frog. It is calculated when an object is in motion. It is given by :

E=(1)/(2)mv^2

$E=(1)/(2)* 0.25\ kg* (2.5\ m/s) ^2$

E = 0.78 Joules

So, the kinetic energy of the frog is 0.78 Joules. Hence, this is the required solution.
