Acceleration Practice Problems: Solving for Distance and Magnitude

In summary, the conversation is about two different assignments, one involving calculating the total distance traveled by an accelerating automobile and the other finding the magnitude of acceleration for a speedboat. The first assignment provides information on the acceleration and speed of the automobile, while the second assignment gives the initial and final speed of the speedboat. Both assignments require equations to be used and the person asking for help is encouraged to provide some effort by providing the variables in symbol form.

I have no clue where to begin with these assignments, can anyone walk through the steps to these?

1. An automobile accelerates from rest at
1.7 m/s2 for 22 s. The speed is then held
constant for 29 s, after which there is an ac-
celeration of −5.8 m/s2 until the automobile
stops.
What total distance was traveled?
Answer in units of km

2. A speedboat increases in speed from 19.3 m/s
to 34.2 m/s in a distance 202 m.
Find the magnitude of its acceleration.
Answer in units of m/

At least give us the variables in symbol form. You've got to show some effort.
 

Related to Acceleration Practice Problems: Solving for Distance and Magnitude

1. What is acceleration?

Acceleration is the rate of change of an object's velocity over time. It is a vector quantity, meaning it has both magnitude (speed) and direction. It is typically measured in meters per second squared (m/s²).

2. How is acceleration calculated?

Acceleration can be calculated by dividing the change in velocity by the change in time. This can be represented by the equation a = (v2-v1)/t, where a is acceleration, v1 is the initial velocity, v2 is the final velocity, and t is the time interval.

3. What is the difference between positive and negative acceleration?

Positive acceleration occurs when an object's velocity is increasing in the direction of motion. Negative acceleration, also known as deceleration, occurs when an object's velocity is decreasing in the direction of motion. This can also be referred to as acceleration in the opposite direction.

4. How does acceleration relate to force?

According to Newton's Second Law of Motion, force is equal to mass times acceleration (F=ma). This means that an object with a larger mass will require a greater force to achieve the same acceleration as an object with a smaller mass.

5. Can acceleration ever be zero?

Yes, acceleration can be zero if an object's velocity remains constant. This can occur if the object is not moving, or if it is moving at a constant speed in a straight line. In these cases, there is no change in velocity over time, so the acceleration is zero.
