QuestionA vehicle with a weight of 5400 N is moving at a speed of $70.0 \mathrm{~km} / \mathrm{h}$. Determine its kinetic energy.
QUESTION 4.

Studdy Solution
Calculate the kinetic energy using the formula $KE = \frac{1}{2} m v^2$:
$$KE = \frac{1}{2} \times 550.46 \, \mathrm{kg} \times (19.44 \, \mathrm{m/s})^2$$ $$KE = \frac{1}{2} \times 550.46 \times 378.09$$ $$KE \approx 104,098.56 \, \mathrm{J}$$
The kinetic energy of the vehicle is approximately:
$$\boxed{104,098.56 \, \mathrm{J}}$$
