Answer: = . /
Explanation:
The acceleration is
= − 0
In our case, the initial velocity has minus sign.
Thus,
=
− (−0)
=
+ 0
Substituting
0 =

8.25 = 7.06 m/s
Answer: = . /
The relationship between frequency and wavelength for an electromagnetic wave is
where
f is the frequency
is the wavelength
is the speed of light.
For the light in our problem, the frequency is
, so its wavelength is (re-arranging the previous formula)
Answer:
The ax versus t graph stays in the range of 2.5 to 3 m/s2 for the first 2 seconds or so, and then it drops quickly to just below 0 m/s2. This corresponds well with the slope of the vx graph: relatively constant positive slope for the first 2.5 seconds, and then zero (and even negative) slope afterwards.
