what is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s? (formula: $ke=\frac{1}{2}mv^{2}$)
Answer
Explanation:
Step1: Identify values
$m = 0.5\ kg$, $v=10\ m/s$
Step2: Apply kinetic - energy formula
$KE=\frac{1}{2}mv^{2}=\frac{1}{2}\times0.5\times(10)^{2}$ $=\frac{1}{2}\times0.5\times100$ $ = 25\ J$
Answer:
25 J
