Question
a)
Two cars are set to race, one can only accelerate at a rate of 2m/s...
a)
Two cars are set to race, one can only accelerate at a rate of 2m/s
starting from rest, and the other can only travel at a set speed of
10 m/s. How fast does each car cover 400 m? Which car would cover a
distance of 400 m faster?
b) If both cars from the previous question started from the
same position, at what time would they have the same displacement?
What is the displacement of the vehicles?
c) A truck covers 40 m in 8.5 seconds while smoothly slowing
down at a constant rate ( acceleration is constant) to a final
speed of 2.8 m/s. Solve for the truck's original speed and it's
acceleration.
d) You are cruising at a speed of 60 mph (26.8 m/s} when a
deer appears 100 m ahead of you. What is the maximum time you have
to stop and what acceleration do you need to have to avoid hitting
the deer?
