Newtons first law states that an object will remain still or in straight line. Until acted upon some force!
Antelope: uniform motion => V = d/t => d = Vt = 7m/s * t
Lion: uniformly accelerated motion, with initial velocity = 0 => d = [1/2]a*t^2 = [1/2]*[5m/s^2]*t^2
7*t = 2.5*t^2=> 2.5t^2 - 7t =0 => t(2.5t - 7) = 0
2.5t - 7 = 0 => t = 7/2.5 = 2.8 m/s^2
Answer:
Explanation:
From the question we are told that
Speed of star 
Distance of spectral line 
Generally the equation for wavelength with respect to spectral lines is mathematically given by
where
therefore
Generally the equation for new wavelength is mathematically given as
Therefore
It depends on the environment around you ... the number and size of
the masses around you, and your distance from their center of mass.
If you happen to be on the surface of the Earth, then
g = 9.8 m/s²
or
g = 9.8 newton/kilogram .
It's different on other planets. Be sure to look it up
before you leave, so you'll know what to expect.
