If the speed of the car changes uniformly, as shown in the graph, this means that the acceleration is constant. As the acceleration is the derivative of the speed

Then, this means that the acceleration is the slope of the equation of the line shown in the graph.

Then, the acceleration of the car is

Answer:
Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element's isotopes. The mass number is a count of the total number of protons and neutrons in an atom's nucleus.
Its average speed is 80 miles per hour because 75 minutes=1.25 hours, and the police car travels 80 miles in 1.25 hours, so I just need to take 100 divided 1.25 equal 80. As a result, the police car travels 80 miles in one hour. Hope it help!
