Remaining = 9,000 - 5,400 = 3,600 kWh
Number of panels = 3,600 ÷ 250 = <<3600/250=14.4>>14.4 → round up to 15
#### 15
Drone KE = (1/2) × 2 × (10)² = 1 × 100 = 100 J
Boulder KE = 0 J (stationary)
Ratio = 100 ÷ 0 → undefined, but since boulder has no kinetic energy, the ratio approaches infinity; however, conventionally, the ratio is considered <<100/0=inf>>undefined or infinitely greater
