Question

A 8kg cat is running 4 m/s. How much kinetic energy does it have?

Answer 1

KE = 1/2 · M · V²

Kinetic energy = (1/2) · (mass) · (speed)²

Cat's KE = (1/2) · (8 kg) · (4 m/s)²

KE = (4 kg) · (16 m²/s²)

KE = 64· (kg ·m² / s²)

KE = 64 · (kg · m / s²) · (m)

KE = 64 Newton · meter

KE = 64 Joules
