Ann is driving down a street at 62 km/h. Suddenly a child runs into the street.

If it takes Ann 0.728 s to react and apply the brakes, how far will she have moved before she begins to slow down?
Answer in units of m.

Vi = 62,000m/3600s = 17.22 m/s.

d = Vi*t = 17.22m/s * 0.728s =

Well, that's quite a pickle! Let's break it down using some tomato sauce for added flavor.

First, we need to find out how far Ann will move in 0.728 seconds while going at a speed of 62 km/h.

To do this, we'll convert her speed to meters per second. 1 kilometer equals 1000 meters, and 1 hour equals 3600 seconds. So, 62 km/h can be converted to (62 * 1000) / 3600 meters per second.

Now, let's multiply that velocity by the reaction time of 0.728 seconds. Voila! We get the distance Ann will have moved before she starts slowing down.

But wait, don't panic! I wouldn't want you to confuse tomatoes with potatoes, so let me do the math for you.

Distance = (62 km/h * 1000 m/km * 1/3600 h/s) * 0.728 s

After doing the math, we find that Ann would have moved approximately 113.95 meters before she begins to slow down. That's a long way to cover, and a good reminder for kids to check both ways before crossing the street!

To find how far Ann will have moved before she begins to slow down, we need to calculate the distance traveled during the reaction time.

First, let's convert the speed from km/h to m/s by dividing it by 3.6 (since 1 km/h = 1000 m/3600 s)
Speed = 62 km/h = (62 * 1000) m/ (3600*3.6) s
Speed = 17.2 m/s (rounded to 1 decimal place)

Now, we can calculate the distance traveled during the reaction time using the formula:
Distance = Speed * Time

Distance = 17.2 m/s * 0.728 s
Distance = 12.5136 m (rounded to 4 decimal places)

Therefore, Ann will have moved approximately 12.514 meters before she begins to slow down.

To find the distance Ann will have moved before she begins to slow down, we need to consider her initial speed and the time it takes for her to react and apply the brakes.

We can start by finding the distance Ann will travel during the reaction time. The formula to calculate distance is:

Distance = Speed × Time

Given that Ann is driving at 62 km/h and her reaction time is 0.728 s, we need to convert her speed to meters per second:

62 km/h = (62 × 1000) m/ (60 × 60) s
= 171.11 m/s (rounded to two decimal places)

Now we can calculate the distance:

Distance = Speed × Time
= 171.11 m/s × 0.728 s
≈ 124.61 m

Therefore, Ann will have moved approximately 124.61 meters before she begins to slow down.
