~ HELPPP PLZZZ (ᗒᗣᗕ) The speed of light is 299792458 m/s ~
Write this speed correct to
3 s. f
6 s. f

3 s.f = 299000000 m/s

6 s.f = 299792000 m/s

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
