Question

a 1,500 kg car is driving at a speed of 20 m/s. how much kinetic energy does the car have? remember : $e_k = \frac{1}{2}mv^2$ $e_k = ?$ j

Explanation:

Step1: Identify given values

Mass \( m = 1500 \, \text{kg} \), speed \( v = 20 \, \text{m/s} \), and the formula for kinetic energy \( E_K=\frac{1}{2}mv^2 \).

Step2: Substitute values into formula

Substitute \( m = 1500 \) and \( v = 20 \) into \( E_K=\frac{1}{2}mv^2 \):

Step3: Calculate the result

\( 750\times400 = 300000 \)

Answer:

\( 300000 \)
