Runner has an initial velocity of 4 meters per second After 20 seconds the runner's velocity is 6 meters per second Which is the runner's acceleration?
Magnitude of average acceleration = (change of speed) divided by (time for the change)Average 'A' = (6 - 4) / 20 = 2/20 = 0.1 meter per second2-- That's the average over the 20 seconds. We don't know anything about thevalue of the acceleration at any particular instant during the 20 seconds.-- We're working entirely with scalars ... speed, not velocity, and magnitude ofacceleration ... since we don't know anything about the runner's direction atany time during the whole event.
What is a runners average speed if he runs 100 meters in 15 seconds?
To calculate the runner's average speed, you would use the formula: speed = distance ÷ time. In this case, the distance is 100 meters and the time is 15 seconds. Therefore, the average speed of the runner would be 100 meters ÷ 15 seconds = 6.67 meters per second.
What is the rate of acceleration of a runner who went from a complete stop to a velocity of 6 meters per second to 12 seconds?
6 m/s divided by 12 s or 0.5 m/s^2. (a half meter per second per second) (on average)
Acceleration is defined as a change in velocity over time if a runner increases velocity from 2 m s to 4 m s over a period of 20 seconds what is the acceleration?
Assuming that acceleration is constant during that time, just divide the change in speed by the time.
If a runner increases velocity from 2 ms to 4 ms over a period of W seconds what is her acceleration?
Average acceleration over a certain time period is the difference in velocity, divided by the time. In this case, (4-2)/W.
What is the velocity in meters per second of a runner who runs exactly 110 m toward the beach in 72 seconds.?
1.53 m/s towards the beach
Runner has an initial velocity of 4 meters per second After 20 seconds the runner's velocity is 6 meters per second Which is the runner's acceleration?

How long does it take to run 300 meters?
Its usually takes an athlete (preferably Usain bolt) 29.9 Seconds to run 300 meters so a high school runner around 39 secs and a college student around 34 seconds depends on the age to be honset and stamana but roughly 30 to 40 seconds 1 minute for the max .
Acceleration is defined as a change in velocity over time . If a runner increases velocity from 2 ms to 4 ms over a period of of A seconds what is her acceleration?
It is 0.1 metre per second-squared.
What is a runners average speed if he runs 100 meters in 15 seconds?
To calculate the runner's average speed, you would use the formula: speed = distance ÷ time. In this case, the distance is 100 meters and the time is 15 seconds. Therefore, the average speed of the runner would be 100 meters ÷ 15 seconds = 6.67 meters per second.
What is the change in a runner's velocity with time?
The change in a runner's velocity with time is determined by their acceleration. If the runner is speeding up, their velocity is increasing, resulting in a positive acceleration. If the runner is slowing down, their velocity is decreasing, resulting in a negative acceleration. Acceleration is the rate of change of velocity with respect to time.
A runner has an initial velocity of 4 meters per second after 20seconds the runners velocity is 6 meter per second what is the runner acceleration?
The runner's acceleration can be calculated using the formula: ( acceleration = \frac{change\ in\ velocity}{time} = \frac{6 m/s - 4 m/s}{20 s} = 0.1 , m/s^2 ). So, the runner's acceleration is ( 0.1 , m/s^2 ).
Find the momentum of a 70kg runner?
The momentum of a 70kg runner can be calculated by multiplying the mass of the runner (70kg) by the velocity of the runner. Without the velocity, we cannot determine the momentum.
What is the average velocity of a runner who completes one lap of a 400m track in 75s?
The average velocity of a runner who completes one lap of a 400m track in 75 seconds is 5.33 m/s. This is calculated by dividing the distance traveled (400m) by the time taken (75s).
Acceleration is defined as a change in velocity over time. if a runner increases velocity from 2 ms to 4 ms over a period of 20 seconds what is her acceleration?
The runner's acceleration is 0.1 m/s^2. This is calculated by taking the change in velocity (4 m/s - 2 m/s = 2 m/s) and dividing by the time taken (20 seconds).
What is the average speed of a runner who completes a 1500 meter race in 4 minutes 10 seconds?
About 365.5 meters a minute.
What is her acceleration if 'acceleration is defined as a change in velocity over time. If a runner increases velocity from 2 ms to 4 ms over a period of 20 seconds?
It is 0.1 metre per second-squared.
