Question

Chapter 3.1, Problem 59E

(a)

To determine

To calculate:

A function in form of height of an object and time to reach the river

(a)

Expert Solution

Answer to Problem 59E

A function in form of height of an object and time to reach the river is h=−16t2+1800 and 3.4 sec .

Explanation of Solution

Given information:

h0=188 ft

Calculation:

Consider,

The height of an object above ground when dropped from initial height h0 : h

So, the linear equation is modeled as:

h=−16t2+h0h=−16t2+1800

Know that: The log reaches the river when the height is zero. So, put h=0 :

0=−16t2+188−16t2=188t2=18816t=±472t≈±3.4

Since t is a negotiate number, then the time t for the log to reach the river is approximately 3.4 sec

(b)

To determine

To calculate:

The value of h(2)−h(3)

(b)

Expert Solution

Answer to Problem 59E

The value of h(2)−h(3) is 80

Explanation of Solution

Given information:

t=2t=3

Calculation:

From sub-part (a):

h(2)−h(3)=[−16(2)2+188]−[−16(3)2+188]h(2)−h(3)=[−64+188]−[−144+188]h(2)−h(3)=124+44h(2)−h(3)=80

This means that the change in height of the log above the ground from t=2 sec and t=3 sec is 80 ft .
