Answer:

The kinetic energy is 22.5J .

Explanation:

Assuming that the formula to find kinetic energy is K.E = 1/2×m×v² where m represents the mass and v is the speed. Then, you have to substitute it :

[tex]k.e = \frac{1}{2} \times m \times {v}^{2} [/tex]

[tex]let \: m = 5,v = 3[/tex]

[tex]k.e = \frac{1}{2} \times 5 \times {3}^{2} [/tex]

[tex] k.e = \frac{1}{2} \times 5 \times 9[/tex]

[tex]k.e = \frac{1}{2} \times 45[/tex]

[tex]k.e = 22.5 \: joules[/tex]
