1) If i start with a velocity of 10m/s and then speed up to 50m/s what is my average velocity, and how far did I go if my total time of travel was 200 seconds

2) What is the acceleration of the car in problem one

Katie L asked:


How I find the displacement of a car in this physics problem?
Here is a chart showing its velocity and time

Time(s)-Velocity(m/s)
0.0——-0.0
1.0——-4.0
2.0——-8.0
3.0——-12.0
4.0——16.0

what is the car’s displacemtn after 4 seconds?

Traveling at a speed of 15.5 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.620. What is the speed of the automobile after 2.10 s have elapsed? Ignore the effects of air resistance.

Suppose that another car is moving with a speed of 18.5 m/s when the brakes are applied os as to slow the car down at a rate of -2.85 m/s^2.
a. What will be the speed of this car 3.55 seconds after the brakes are applied?
b. How far will this car move during this 3.55 second period?
c. How long will it take for this car to stop?
d. How afar will this car move from the time that the brakes ar applied until the car comes to a stop?

when you use a graph to solve a problem about how far a car traveled during a specified time during which it was accelerating. how many area calculation do you have to make?what is/are the shape/shapes you are calculating
