Question

Find the kinetic energy of a 0.1-kilogram toy truck moving at the speed of 1.1 meters per second.

Answer 1

Answer:

0.061 J

Explanation:

The kinetic energy of an object is given by

$K=\frac{1}{2}mv^2$

where

m is the mass of the object

v is its speed

For the toy truck in the problem, we have

m = 0.1 kg is its mass

v = 1.1 m/s is its speed

Putting the numbers into the equation, we find

$K=\frac{1}{2}(0.1 kg)(1.1 m/s)^2=0.061 J$
