a.
Explanation:
Remeber speed and velocity are the same concept, it just speed is scalar, meaning it doesn't have a direction nor it negative.
So technically thr car had a constant speed over 75 seconds.
If thr car has a constant speed, the car isn't speeding up or slowing down so it has accleration of 0 so the answer is a.
Answer:
70 mph
Explanation:
We can write the position of the car at time t as
where is the speed of the car, while the position of the truck is
where
is the initial distance between the car and the truck (at 3:00 pm)
is the speed of the truck
The car overcomes the truck when they have same position, so
This occurs at 4:30 pm, so 1:30 h (1.5 h) after the initial instant. So, by using
t = 1.5 h
And solving the equation for , we find the speed of the car:
Answer:
The answer is C. 120,000 J.
