Answer:
The kinetic energy of a 90 kg mass that is moving with a velocity of 6 m/s is 1620 J.
Explanation:
Given
To determine
The kinetic energy (K.E) of a body of mass of a 90 kg mass that is moving with a velocity of 6 m/s can be calculated using the formula
where
- K.E is the Kinetic energy (J)
substituting m = 90 and v = 6 in the formula
J
Therefore, the kinetic energy of a 90 kg mass that is moving with a velocity of 6 m/s is 1620 J.
Answer: I believe his brother, Mike, who is 6'2, will have the longer shadow.
The answer, of course, does indeed depend on what one means by “move around,” and in particular the comments refer to the notion of a “reference frame.” I can think of at least three different things one might mean by that phrase. First there is the idea of a “global reference frame.” The second notion is that of an “inertial reference frame.” Inertial frames are actually a subset of all possible global frames; in particular, they are the global frames in which free (unaccelerated) particles appear to move on straight lines. <span>Finally, we have the more flexible notion of a “coordinate system.” Unlike a global frame or the even-more-restrictive inertial frame, a coordinate system can be set down throughout space in any old way, so long as it assigns unique coordinates to each point. </span>
