The shortest visible wavelength is the last color you can see
at the blue end of the spectrum.

The light-gathering capacity of a telescope depends on the area
of the main lens in the front, or the main mirror in the back.
That's also the area of the opening of the tube, called the 'aperture'.

A toy car is given an initial velocity of 5.0 m/s and experiences a constant acceleration of 2.0 m/s656-03-02-00-00_files/i02900
Whitepunk [10]
It would be 17 m/s

If we use

V2 = V1 + a*t
Sub in 5 for v1
2m/s*2 for a
And
6 for t
That should give you the answer.
