Answer:
240,000 J or 240 kJ
Explanation:
We can use the equation for kinetic energy:
KE = [tex]\frac{1}{2}mv^{2}[/tex]
where m = mass and v = velocity
Next, substitute the known values into the equation:
- mass = 1200 kg
- velocity = 60m in 3 seconds → 60/3 = 20 m/s
KE = 1/2 × 1200 × 20² = 240,000 J
Answer: 240,000 J or 240 kJ
Hope this helps!
