Solution 1

To solve this problem, we can use the equation of motion that relates final velocity, initial velocity, acceleration, and distance. The equation is:

v^2 = u^2 + 2as

where: v is the final velocity, u is the initial velocity, a is the acceleration, and s is the distance.

We can rearrange the equation to solve for s:

s = (v^2 - u^2) / 2a

Substituting the given values:

s = ((30.0 m/s)^2 - (10.0 m/s)^2) / (2 * 3.00 m/s^2) s = (900 m^2/s^2 - 100 m^2/s^2) / 6.00 m/s^2 s = 800 m^2/s^2 / 6.00 m/s^2 s = 133.33 m

So, the car travels approximately 133.33 meters while accelerating.

Solution 2

To solve this problem, we can use the equation of motion that relates final velocity, initial velocity, acceleration, and distance traveled. This equation is:

v^2 = u^2 + 2as

where: v is the final velocity, u is the initial velocity, a is the acceleration, and s is the distance traveled.

We can rearrange this equation to solve for s:

s = (v^2 - u^2) / (2a)

Substituting the given values:

s = ((30.0 m/s)^2 - (10.0 m/s)^2) / (2 * 3.00 m/s^2) s = (900 m^2/s^2 - 100 m^2/s^2) / 6.00 m/s^2 s = 800 m^2/s^2 / 6.00 m/s^2 s = 133.33 m

So, the car travels approximately 133.33 meters while accelerating.
