Answer

Explanation:

Step1: Substitute values into formula

Given (m = 54\space kg) and (v = 3\space m/s), substitute into (KE=\frac{1}{2}mv^{2}). (KE=\frac{1}{2}\times54\times3^{2})

Step2: Calculate (3^{2})

(3^{2}=9), so the formula becomes (KE=\frac{1}{2}\times54\times9).

Step3: Calculate (\frac{1}{2}\times54)

(\frac{1}{2}\times54 = 27), then (KE=27\times9).

Step4: Calculate (27\times9)

(27\times9=243).

Answer:

243 J
