Question

A 0.12 kg paper airplane flies in a straight line at a speed of 1.3 m/s. How much kinetic energy does the airplane have?

Answer 1

0.1014 J

Step-by-step explanation:

Considering the air resistance negligible kinetic energy is given by

K.E = (1/2) m v^2

K.E = 0.5 x 0.12 x (1.3)^2

K.E = 0.06 x 1.69

K.E = 0.1014 J
