Answer:

[tex] \boxed{\sf Kinetic \ energy \ of \ the \ bear (KE) = 23002.1 \ J} [/tex]

Given:

Mass of the polar bear (m) = 6.8 kg

Speed of the polar bear (v) = 5.0 m/s

To Find:

Kinetic energy of the polar bear (KE)

Explanation:

Formula:

[tex] \boxed{ \bold{\sf KE = \frac{1}{2} m {v}^{2} }}[/tex]

Substituting values of m & v in the equation:

[tex] \sf \implies KE = \frac{1}{2} \times 380.2 \times {11}^{2} [/tex]

[tex] \sf \implies KE = \frac{1}{ \cancel{2}} \times \cancel{2} \times 190.1 \times 121 [/tex]

[tex] \sf \implies KE = 190.1 \times 121 [/tex]

[tex] \sf \implies KE = 23002.1 \: J[/tex]

[tex] \therefore [/tex]

Kinetic energy of the polar bear (KE) = 23002.1 J
