A married couple is driving on a dark road at night at the rate of 98.0 m/s until they see a clown 50m in front of them and slam the brakes to slow the car down to 10.0m/s and still manage to hit the clown. How much time would the clown have had to move before being roadkill? Determine the average velocity of the married couples car.
V = Vo + a*t.
V = 10 m/s.
Vo = 98 m/s.
a = (V^2-Vo^2)/2d. It will be negative.
t = ?.
To find out how much time the clown would have had to move, we need to calculate the time it took for the car to slow down from 98.0 m/s to 10.0 m/s.
The initial velocity of the car is 98.0 m/s, and the final velocity is 10.0 m/s. We can use the formula for acceleration to find the time:
a = (vf - vi) / t
where a is the acceleration, vi is the initial velocity, vf is the final velocity, and t is the time.
Rearranging the formula to solve for t:
t = (vf - vi) / a
In this case, the acceleration (a) is negative because the car is slowing down.
a = (10.0 m/s - 98.0 m/s) / t
Now we can solve for t:
t = (10.0 m/s - 98.0 m/s) / (-a)
To find the average velocity of the married couple's car, we can use the formula for average velocity:
average velocity = total displacement / total time
Since the car stopped after hitting the clown, the total displacement is the distance between the clown and the initial position of the car, which is 50 meters. We just calculated the time it took for the car to stop, which is the total time.
Now we can calculate the average velocity:
average velocity = 50 m / t
To solve these equations, we need to know the value of the acceleration (a). It is not provided in the question, so we cannot find the exact answer without this information.
However, by following the steps and formulas provided, you can answer the question once you know the value of the acceleration.
