## Motion in one dimension – quiz answers

The term “one dimension” refers to the body’s ability to move only in one plane and in a straight line. For example, if we roll a marble on a flat table in a straight line (which is difficult! ), it will be in one-dimensional motion.
This motion can be defined using four variables combined in an equation. Initial Velocity (u), Final Velocity (v), Acceleration (a), Distance Traveled (s), and Time Elapsed are the variables to consider (t). These are the equations that show the relationship between these variables.

## Physics 2 – motion in one-dimension (8 of 22) example 1

Explanation: Using the equation, we can calculate the distance traveled by the ball. It’s worth noting that the ball’s mass is irrelevant in this problem. We’re advised that the ball is dropped from the rest, so we’ve got. We notice that = 125m when we plug in our values and assume that acceleration is equal to gravity (10m/s2).
You’re driving at a high rate when a tree falls across the lane, blocking your way. To avoid colliding with the fallen tree, you slam on your brakes and come to a complete stop. When you hit the brakes, you were a good distance away from the tree. What is the minimum deceleration needed to avoid hitting the fallen tree, assuming your vehicle does not skid?
A is thrown from a height of and lands on the ground. When the ball is off the ground, a photo is taken with an exposure time of. What would the vertical diameter of the ball tend to be in the picture if the real diameter of the ball is?
Explanation: The first step in solving this problem is to determine the ball’s velocity at the time the photograph is taken. We know the ball’s initial velocity (zero), displacement, and acceleration. We can solve for the final velocity using the necessary kinematics formula.

1.Amitabh Bachchan was waiting for his beloved Amrita Singh with his dog during the filming of the super hit MARD. The dog was delighted when he saw her coming and ran to her, then back to owner, and so on, never stopping. If the dog ran at 30 km/h and the humans walked at 4 km/h, how far would you estimate the dog ran if they started from a distance of 400 meters apart?

### Problems in one dimensional motion

The equation isn’t the most straightforward for this case, but it can be used in this situation, and here’s how. 21.1 m/s is calculated by dividing the displacement, 110 m, by the period, 5.21 s. That is, however, the average velocity over the entire distance. When v changes uniformly, the average velocity is calculated by adding the initial and final velocities and dividing by two. Since the initial velocity is 0 m/s, you must double the 21.1 m/s for the final velocity to get the measured 21.1 m/s average. As a result, the final velocity, and thus the velocity shift over that distance, is 42.2 m/s. The amount of delta v per second, acceleration, is calculated by dividing the delta v by the time it occurs.
Yes, I believe so. The proper formula for calculating the distance traveled by an object accelerating at a constant rate over time is given below. I used it to create a formula that calculates acceleration based on distance and time traveled.
