The distance-time graph shows that the object initially travels 2 meters in 2 seconds, indicating a speed of 1 m/s for that segment. Subsequently, it travels 80 meters in 40 seconds, resulting in an average speed of 2 m/s for that segment. Overall, the graph reflects two different speeds during the object's journey, with the second segment being slower than the first. The overall distance covered is 82 meters in a total of 42 seconds.

total distance = 2m + 80m = 82 m total time = 2s + 40s = 42s → average speed = total distance / total time = 82m / 42s = 1 20/21 m/s ≈ 1.95 m/s
Stopping distance is comprised of three main components: perception distance, reaction distance, and braking distance. Perception distance is the distance a vehicle travels while the driver recognizes a need to stop. Reaction distance is the distance covered during the driver's reaction time before applying the brakes. Finally, braking distance is the distance the vehicle travels from the moment the brakes are applied until it comes to a complete stop.
In general, we will find the average speed of a moving object by dividing the total distance it travels by the total time elapsed in its travel.We can find the actual speed of the object if it moves with a constant speed during all of its travel. But if the object is something like a bus or train that makes stops along the way, we discover its average speed by dividing the total distance it travels by the total time it took to travel that distance.
Not enough information. You also need to know how much the acceleration is. Once you know that, calculate the final speed, then calculate the average speed as (initial speed + final speed) / 2, and multiply that by the time to get the distance.

The distance a baseball travels during a home run hit can vary, but it is typically between 350 to 450 feet.

Energy travels from one place to another during a wave motion. Particles in the medium may also oscillate in place as the wave passes through, but they do not permanently move from one location to another.
total distance = 2m + 80m = 82 m total time = 2s + 40s = 42s → average speed = total distance / total time = 82m / 42s = 1 20/21 m/s ≈ 1.95 m/s
No, light refraction does not increase during distance vision. Light refraction occurs when light travels from one medium to another of different optical density, causing it to change direction. The amount of refraction is determined by the difference in optical density between the two mediums, not by the distance of the object being viewed.
The greatest distance the knot travels from its resting position is called the amplitude. This measures the maximum displacement of the knot from its equilibrium position during its oscillation.
During a single period a wave travels just one wavelength.
Light travels at a slower speed in glass compared to vacuum. The ratio of the speed of light in vacuum to the speed of light in glass is called the refractive index of glass. So, the distance light travels in glass would be the distance it travels in vacuum divided by the refractive index of glass.
Answer: The average speed of the object is 1.95 m/s. Explanation: Distance traveled by an object in the first interval, = 2 m Time is taken in firsts interval = 2 s Distance traveled by an object in the second interval, = 80 mm Time taken in second interval = 40 s The average speed of the object is 1.95 m/s.

During refraction, a wave changes direction due to the change in speed as it travels from one medium to another, causing the wavefronts to bend. This change in direction occurs because the wave changes its propagation speed and hence its angle of incidence with respect to the normal.
