Solution Steps

Step 1: Identify the Given Values

We are given:

  • The force exerted (weight of the lawn mower), \( F = 200 \, \text{N} \)
  • The height the lawn mower is lifted, \( h = 1.1 \, \text{m} \)
Step 2: Understand the Work Formula

The work done \( W \) is calculated using the formula: \[ W = F \cdot d \] where \( F \) is the force and \( d \) is the distance (height in this case).

Step 3: Calculate the Work Done

Substitute the given values into the formula: \[ W = 200 \, \text{N} \times 1.1 \, \text{m} \] \[ W = 220 \, \text{J} \]

Final Answer

\(\boxed{220 \, \text{J}}\)

The answer is c 220 J.

Write a program to test the functions described in Exercises 11 and 14 of this chapter. Instructions for Exercise 11 and Exercise 14 have been posted below for your convenience. Exercise 11 Write the definition of a function that takes as input a char value, and returns true if the character is a whitespace character; otherwise it returns false. If the character is a whitespace character, output the following message: The character you entered is a whitespace character, otherwise output: The character you entered is not a whitespace character. Exercise 14 Write the definition of a function that takes as input three numbers. The function returns true if the floor of the product of the first two numbers equals the floor of the third number; otherwise it returns false. (Assume that the three numbers are of type double.) Output the appropriate message: The product of the first two numbers is not equal to the floor of the third number or The product of the first two numbers is equal to the floor of the third number
