Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

e Inquiry into Physics, Loose-Leaf Version
< Chapter 3, Problem 20P
Formula used:
The kinetic energy of an object is given as
KE = mv²
Here.
m is the mass
v is the velocity.
Calculation:
The speed of the dart is calculated by the formula
KE = mv²
Plugging the values in the above equation
0.5 = x 0.02v2
v = 7.07 m/s
Conclusion:
Speed of the dart when it just leaves the gun is 7.07 m/s.
