Toy Airplane Kinetic Energy Calculation

How much kinetic energy does the 120-gram toy airplane have?

A. 0.1014 J

B. 101.4 J

C. 0.014 J

D. 1.014 J

Answer: A. 0.1014 J

To calculate the kinetic energy of the toy airplane, we use the formula: KE = 0.5 * m * v^2. Where KE is the kinetic energy, m is the mass of the airplane, and v is the speed of the airplane.

Given that the mass of the toy airplane is 120 grams (0.12 kg) and the speed is 1.3 m/s, we plug the values into the formula:

KE = 0.5 * 0.12 * 1.3^2 = 0.1014 J

Therefore, the kinetic energy of the 120-gram toy airplane is 0.1014 Joules.
