what is the kinetic energy of a 1,600kg mustang travelling at 15 m/s (33mph)\n1225 j\n3920000 j\n294 j\n180000 j
Answer
Explanation:
Step1: Recall kinetic - energy formula
The formula for kinetic energy is $K = \frac{1}{2}mv^{2}$, where $m$ is the mass and $v$ is the velocity.
Step2: Identify given values
$m = 1600\ kg$ and $v = 15\ m/s$.
Step3: Substitute values into formula
$K=\frac{1}{2}\times1600\times(15)^{2}$. First, calculate $(15)^{2}=225$. Then, $\frac{1}{2}\times1600 = 800$. So, $K = 800\times225=180000\ J$.
Answer:
D. 180000 J
