A muon (an elementary particle) enters a region with a speed of 4.85 × 10^6 m/s and then is slowed at the rate of 1.63 × 10^14 m/s^2. How far does the muon take to stop?

Explanation:
The muon take .0721 m to stop
Explanation:
I-------------------------------------------------------------------------l
a = 1.63 x
Don't worry about the dashes between a and x
and
v is the final velocity when the muon stop
x is the position muon stop (in meters)
a is the acceleration
To find out how far does the muon need to stop, we could use the constant acceleration equation
Why this equation, since we know what v,
If we plug in v and
We can rewrite the equation as x = (
so
x =
So x = .0721 m
This is just one way you could solve the answer.
