Work=Force x Distance
2x25=50
The correct answer is C
this is the best answer for you
When two objects collide there will be a force acting on them both and their individual kinetic energies and momenta may alter. As you know already, energy is always conserved but in a collision some, or all of the kinetic energy may be ... of the same mass and traveling at the same speed but in opposite directions collided ...

Answer:
It will take 29.31 seconds for the Boxster to catch the Scion
Explanation:
Given the data in the question;
lets say Toyota Scion xB is car A and Porsche Boxster convertible is B and Toyota Scion xB is car A
the distance travelled by car A is
x =
× t
where
is the speed of the car and t is time
the distance travelled by car B before reaching car A will be;
x + x₀ =
× t
Now lets replace x by
× t
so
(
× t) + x₀ =
× t
x₀ = (
× t) - (
× t)
x₀ = t (
-
)
t = x₀ / (
-
)
so we substitute
t = 170 m / (24.4 - 18.6)
t = 170 / 5.8
t = 29.31 s
Therefore; it will take 29.31 s for the Boxster to catch the Scion
