A) Both players are moving by uniformly accelerated motion, and we can write the position at time t of each of the two players as follows:
where
is the acceleration of the first player
is the acceleration of the second player
is the initial distance between the two players
and where I put a negative sign in front of the acceleration of the second player, since he's moving in the opposite direction of the first player.
The time t at which the two players collide is the time t at which
, therefore:
from whic we find
b) We can use the equation of
to find how far the first player run in t=8.5 s:
where
and where I put a negative sign in front of the acceleration of the second player, since he's moving in the opposite direction of the first player.
The time t at which the two players collide is the time t at which
from whic we find
b) We can use the equation of
