calculate the kinetic energy of a 94 kg scooter moving at 8.0 m/s.\n752 j\n3008 j\n376 j\n6016 j

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: Substitute given values

Given $m = 94\ kg$ and $v = 8.0\ m/s$. Substitute into the formula: $K=\frac{1}{2}\times94\times(8.0)^{2}$.

Step3: Calculate

First, $(8.0)^{2}=64$. Then, $\frac{1}{2}\times94\times64 = 47\times64=3008\ J$.

Answer:

B. 3008 J
