Question

A giant bat has an average mass of 250g. suppose a bat with this mass flies at 2.0m/s when it detects a giant bug

Answer 1

Question

Determine its kinetic energy

Answer:

0.5 J

Explanation:

Kinetic energy is given by

$KE=0.5mv^{2}$ where m is the mass and v is the speed

Substituting 250g= 0.25 Kg for mass and 2 m/s for v then

$KE=0.5\times 0.25\times 2^{2}$=0.5 J
