Acceleration=9.81m/s^2
initial velocity=0m/s
time=.28s
We have to find final velocity.
The equation we use is
Final velocity=initial velocity+acceleration x time
Vf=0m/s+(9.81m/s^2)(.28s)
Vf=2.7468m/s
We would round this to:
Vf (final velocity)=2.7m/s
High frequency = D, short wavelength
(100, 108)
Due to
1.2x90=108

Refraction is the bending of light<span> </span>
S=Vt
110=V(72)
110/72=V
V=1.527m/s
