Car's Motion Analysis: Reflecting on Velocity, Acceleration, and Distance
What are the key elements of the car's motion from point P to point Q?
The car accelerates uniformly, moves at a constant speed, and decelerates uniformly.
What is the uniform acceleration of the car?
The uniform acceleration of the car can be calculated using the formula: Acceleration = (Final velocity - Initial velocity) / Time.
What is the uniform deceleration of the car?
The uniform deceleration of the car can be calculated using the same formula as acceleration, but with the final velocity as 0 m/s.
How can we calculate the distance from point P to point Q?
The distance can be calculated using the equation: Distance = Initial velocity × Time + (1/2) × Acceleration × Time^2.
Answer:
The car's velocity-time graph consists of acceleration, constant speed, and deceleration phases. The uniform acceleration and deceleration can be found using the velocity formula, and the distance can be calculated using the distance formula.
Explanation:
The velocity-time graph of the car's motion from point P to point Q will consist of three parts: an increasing slope representing acceleration, a constant horizontal line representing constant speed, and a decreasing slope representing deceleration.
The uniform acceleration of the car can be found using the formula: Acceleration = (Final velocity - Initial velocity) / Time.
The uniform deceleration of the car can also be found using the same formula, but with the final velocity as 0 m/s.
To calculate the distance from point P to point Q, we can use the equation: Distance = Initial velocity × Time + (1/2) × Acceleration × Time^2.
