A rock is dropped off the edge of a cliff and its distance s (in feet) from the top of the cliff after t seconds is s(t) = 16. Assume the distance from the top of the cliff to the water below is 144 ft. Answer part (a) and (b). (a) When will the rock strike the water? The rock will strike the water at seconds. (Type an integer or a simplified fraction.) (b) Make a table of average velocities and appraximate the velocity at which the rock strikes the water. 2 999, 3 Time Interval Average Velocity (A/sec) (Type an integer or decimal rounded to three decimal places as needed.) 12. 3 25, 3 29. 3 2. 99, 3 The rock strikes the water at approximately t/sec. (Round to the nearest integer as needed)
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.
