Answer:
b)
Explanation:
According Newton's 2nd Law, the net force on an object (assuming we can consider it like a point mass), produces an acceleration on the mass of the object, expressed in this way:
Fnet = m*a (1)
By definition, the acceleration is the rate of change of velocity:
[tex]a =\frac{(vf-vo)}{t-to}[/tex]
If we choose t₀ = 0, we can see that if we measure vf and v₀, as time is known, we can get the value of a.
Using a balance to determine the mass of the car, and replacing all the values in (1), we can get the magnitude of the net force exerted on the car during the 5 s that the car accelerates, as required.
Answer:
What speed is the car traveling at the longest distance and the shortest distance, and how do they compare?"
"Does the car move faster or slower for longer distances?"
