Motion and graphs of motion formative

Marco wants to buy the used sports car with the greatest acceleration.

Car A can go from 0 m.s^-1 to 18,9m.s^-1 in 4,00 s. Car B can accelerate from 0 m.s^-1 to 22,4 m.s^-1 in 3,50 s. Car C can go from 0 to 26,8 m.s^-1 in 6,00 s. Rank the three cars from greatest

acceleration to least.

What quantity is the rate of change of velocity?

The velocity vs time graph for the motion of a car on a straight road is shown in the graph. Assume that the car starts at the origin 𝓍 = 0 at time t = 0.

If the car's initial velocity is east, then after 10 s is the car's position east or west from its starting point?

The velocity vs time graph for the motion of a car on a straight road is shown in the graph. Assume that the car starts at the origin 𝓍 = 0 at time t = 0.

During which time interval is the car speeding up?

Which swimmer swam the furtherest?

When was the object experiencing constant acceleration?

Select all that apply.

Consider the following distance vs time graph showing the motion of two cars, car A and car B. How far has car A travelled when the cars pass each other?

Consider the following distance vs time graph showing the motion of two cars, car A and car B. How do the speeds of the cars compare?

The graph shows the velocity of an object over time.

Which one of the following options correctly shows how the acceleration of the object changes with time?
