what is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s? (formula:ke = 1/2 mv²) 25 j 5 j 50 j 100 j
Answer
Explanation:
Step1: Identify values
$m = 0.5$ kg, $v=10$ m/s
Step2: Substitute into formula
$KE=\frac{1}{2}\times0.5\times(10)^2$ $KE = \frac{1}{2}\times0.5\times100$ $KE=25$ J
Answer:
A. 25 J
