Answer:

Kinetic Energy is 147 J

Explanation:

[tex]{ \rm{kinetic \: energy = \frac{1}{2} \times mass \times velocity {}^{2} }} \\ \\ { \rm{k.e = \frac{1}{2} \times 6 \times {7}^{2} }} \\ \\ { \rm{k.e = 3 \times 49}} \\ \\ { \boxed{ \rm{k.e = 147 \: joules}}}[/tex]

Hi there!

Recall the equation for kinetic energy:

[tex]\large\boxed{KE = \frac{1}{2}mv^2}}[/tex]

KE = Kinetic energy (J)

m = mass (kg)

v = velocity (m/s)

Plug in the given values:

[tex]KE = \frac{1}{2}(6)(7^2) = \boxed{147 J}[/tex]
