A car comes to a stop six seconds after the driver applies the brakes. While the brakes are on, the following velocities are recorded: Time since brakes applied 4 (sec) Velocity (ft/sec) 81 56 14 Give lower and upper estimates for the distance the car traveled after the brakes were applied. Lower estimate = i ft Upper estimate ft 6 2.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![## Estimating the Distance a Car Travels After Braking
### Problem Statement:
A car comes to a stop six seconds after the driver applies the brakes. The following velocities were recorded over that period:
| Time since brakes applied (sec) | 0 | 2 | 4 | 6 |
|---|---|---|---|---|
| Velocity (ft/sec) | 81 | 56 | 14 | 0 |
### Objective:
Give lower and upper estimates for the distance the car traveled after the brakes were applied.
### Instructions:
For calculating the lower and upper estimates of the distance, please provide the values in the respective fields below:
**Lower estimate** (in feet): [ ______ ] ft
**Upper estimate** (in feet): [ ______ ] ft](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3190a26b-07a4-4acc-b1dd-52ddc1659ccb%2Fbc16807e-7274-44e7-b0b7-726afcc1df7f%2Fs1yguk_processed.jpeg&w=3840&q=75)
