Question

A race car travel on a racetrack at 44m/s and slows down at a constant rate to a velocity of 22m/s over 11s. How far does it move during this time

Answer 1

The race car moves a distance of 484 meters during this time.

Step-by-step explanation:

To find how far the race car moves during this time, we can use the equation:

displacement = initial velocity * time + 1/2 * acceleration * time^2

Given that the initial velocity of the race car is 44 m/s, the final velocity is 22 m/s, and the time is 11 s, we can plug these values into the equation:

displacement = 44 m/s * 11 s + 1/2 * 0 * (11 s)^2

Simplifying the equation, we get:

displacement = 484 m

Therefore, the race car moves a distance of 484 meters during this time.
