Final answer:
The question deals with static friction and requires determining if a coefficient of 0.675 is enough to prevent a 150.0-kg crate from sliding in a slowing truck. It encompasses physics concepts like friction, force, mass, and acceleration.
Step-by-step explanation:
Understanding Static Friction in Physics
The question revolves around the concept of static friction and its role in preventing a 150.0-kg crate from sliding on the bed of a truck. The truck experiences a deceleration as it slows down from 56.0 km/h to a stop over a 12.0-second duration. The main objective is to establish whether the given coefficient of static friction of 0.675 is sufficient to keep the crate from slipping during the truck's deceleration.
Step-by-Step Conceptual Approach
- Identify the crate's mass and the deceleration rate of the truck.
- Calculate the force of static friction needed to prevent slipping based on the mass of the crate and the deceleration.
- Compare the available static friction force, derived from the coefficient of static friction and the crate's weight, against the needed force to prevent slipping.
The process involves understanding basic kinematic equations, Newton's laws of motion, and the principles of friction, which are fundamental components in high school physics coursework.
