Question

kyle has a mass of 54 kg and is jogging at a velocity of 3 m/s. what is kyles kinetic energy? (formula: $ke=\frac{1}{2}mv^{2}$)
18 j
81 j
162 j
243 j

Explanation:

Step1: Identify values

$m = 54$ kg, $v=3$ m/s

Step2: Substitute into formula

$KE=\frac{1}{2}mv^{2}=\frac{1}{2}\times54\times3^{2}$

Step3: Calculate

$\frac{1}{2}\times54\times9 = 243$ J

Answer:

243 J
