Question
A car accelerates from 10.0 m/s to 30.0 m/s at a rate of 3.00 m/s2.How far does the car travel while accelerating?Express your answer in meters.
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.
