Question

The kinetic energy of a 7.3 kg steel ball traveling at 18.0 m/s is ___ J.
Options
A 1.2 × 10³
Correct Answer
B 66
C 2.4 × 10³
D 1.3 × 10²
Correct Answer

Option A is the correct answer.

Detailed Explanation

KE = ½mv² = 0.5 × 7.3 kg × (18.0 m/s)² = 0.5 × 7.3 × 324 = 1182.6 J ≈ 1.2 × 10³ J.

Hint

Use KE = ½mv².
