Answer:
Explanation:
A body has acceleration when there is a change in the velocity vector, either in magnitude or direction. In this case we only have a change in magnitude. The average acceleration represents the speed variation that takes place in a given time interval.
a)
b)
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
