a) When does the top of the ladder reach the ground? b) Determine the velocity of the end of the ladder that is resting on the ground when it is 5 ft from the wall.
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.

**Problem 19**
A 13-foot ladder is leaning against a wall. A gust of wind causes the ladder to slide so that the foot of the ladder is 1 foot from the wall. The motion of the top of the ladder as it slides down the wall is described by:
\[ y = -16t^2 + 0.5t + \sqrt{168} \]
where \( t \) is measured in seconds.
a) When does the top of the ladder reach the ground?
b) Determine the velocity of the end of the ladder that is resting on the ground when it is 5 feet from the wall.

This setup describes a physics problem involving a ladder sliding down a wall due to a gust of wind. The equations of motion are given for the position of the ladder's top as a function of time, and questions pertain to calculating specific points in this motion.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0d5a9cae-3c86-4153-9ed8-d2e45fd1e238%2Fa4e81edc-ffe9-4b52-af49-71772b1412a3%2F7haxdxy_processed.jpeg&w=3840&q=75)
