Question

What is the kinetic energy of a 1500 kg car traveling at 20.0 m/s?
Options
A 3.0 × 10² J
B 3.0 × 10⁴ J
C 3.0 × 10⁵ J
Correct Answer
D 6.0 × 10⁵ J
Correct Answer

Option C is the correct answer.

Detailed Explanation

KE = ½mv² = 0.5 × 1500 kg × (20.0 m/s)² = 0.5 × 1500 × 400 = 300,000 J = 3.0 × 10⁵ J.

Hint

Use KE = ½mv².
