When we talk about how a Ferrari obtains a top speed of 349 km/h, are we referring to average speed or instantaneous? How do you know?

Answer:
Instantaneous
Explanation:
The top speed of a car refers to its instantaneous speed. The average speed is the total distance it travels divided by the time it takes.
The answer is [ instantaneous ]
The average speed of a car is the speed the car keeps constant through a certain distance. Notice how the questions says the Ferrari reaches a top speed of 349km/h. The top speed is not the same as the average speed. Instantaneous means done right at that moment. The top speed was reached once and at that specific moment which makes that the correct answer.
Best of Luck!

Answer:
d = 100.8 ft
Explanation:
As we know that initial speed of the van is 40 miles then the stopping distance is given as 70 feet
here we know that
so here we have
now again if the speed is increased to 48 mph then let say the stopping distance is "d"
so we will have
now divide the above two equations

Answer:
6858.5712 m/s
Explanation:
Given that:
Radius, r
R = 3.20 * 10^3.
Normal force = 0.5 * normal weight
Normal force = Fn ; Normal weight = Fg
Fn = 0.5Fg
Recall:
mv² / R = Fn + Fg
Fn = 0.5Fg
mv² / R = 0.5Fg + Fg
mv² /R = 1.5Fg
mv² = 1.5Fg * R
F = mg
mv² = 1.5* mg * R
v² = 1.5gR
v = sqrt(1.5gR)
V = sqrt(1.5 * 9.8 * 3.2 * 10^3)
V = sqrt(47.04^3)
V = 6858.5712 m/s
