what is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s? (formula: $ke=\frac{1}{2}mv^{2}$)\n25 j\n5 j\n50 j\n100 j

Answer

Explanation:

Step1: Identify values

$m = 0.5\ kg$, $v=10\ m/s$

Step2: Substitute into formula

$KE=\frac{1}{2}\times0.5\times(10)^2$

Step3: Calculate

$KE=\frac{1}{2}\times0.5\times100 = 25\ J$

Answer:

A. 25 J
