Chapter 1.3, Problem 22PPSE

Solution

To state: The distance the object falls during $2$ seconds if expression $16t^2$ models the distance in feet that an object falls during the first t seconds after being dropped.

The object will fall a distance of 64 feet for the first 2 seconds.

Given information:

The given expression is $16t^2$ . The value of t is 2 seconds.

Explanation:

An expression that has been created using mathematical operators, grouping symbols, variables, and integers is called an algebraic expression.

Consider the given expression $16t^2$ :

  $16t^2$

Substitute the values of variable t as 2 into the given expression,

  $16{\left(2\right)}^2$

Simplify the power,

  $16\left(4\right)$

Multiply,

  $64$

Therefore, the distance the object falls during 2 seconds is 64 feet.
