Question

45.
which graph represents the relationship between the kinetic energy and the speed of a freely falling object?

a 30.4-newton force is used to slide a 40.0-newton crate a distance of 6.00 meters at constant speed along an incline to a vertical height of 3.00 meters.

81.
determine the total work done by the 30.4-newton force in sliding the crate along the incline.

82, 83.

Explanation:

Step1: Recall Work Formula

Work \( W \) is calculated as \( W = F \cdot d \), where \( F \) is force and \( d \) is distance in the direction of force.

Step2: Identify Values

Given \( F = 30.4 \, \text{N} \) and \( d = 6.00 \, \text{m} \).

Step3: Calculate Work

Substitute into formula: \( W = (30.4 \, \text{N})(6.00 \, \text{m}) \).
\( W = 182.4 \, \text{J} \)

Answer:

\( 182.4 \, \text{joules} \)
