Question

what is the ke of a 6 kg mass at 4 m/s?

Explanation:

Step1: Write the kinetic energy formula

The formula for kinetic energy (\(KE\)) is \(KE=\frac{1}{2}mv^{2}\), where \(m\) is the mass and \(v\) is the velocity.

Step2: Substitute the given values

Given \(m = 6\space kg\) and \(v=4\space m/s\). Substitute into the formula: \(KE=\frac{1}{2}\times6\times(4)^{2}\).
First, calculate \((4)^{2}=16\). Then \(\frac{1}{2}\times6 = 3\).

Step3: Calculate the final value

Multiply \(3\times16\).

Answer:

\(48\space J\)
