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 the
value of the acceleration at any particular instant during the 20 seconds.
-- We're working entirely with scalars ... speed, not velocity, and magnitude of
acceleration ... since we don't know anything about the runner's direction at
any time during the whole event.

An arrow in flight has an initial velocity of 65 meters per second and 10 seconds later it has a velocity of 35 meters per second Which is the acceleration of the arrow?
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
What is a cars acceleration if it travels 0 to 55 miles per hour in 6 seconds?
Acceleration = Change in Velocity / Change in Time a = (Final Velocity - Initial Velocity) / (Final Time - Initial Time) = (55-0)/(5-0) = 55/5 a = 11 m/s^2
A braking time of 1.5 to 2 seconds what is the final velocity?
You need more details.The final velocity could be 0However, you need to know the initial velocity, and the braking acceleration, and perhaps other acceleration/deceleration factors to know the true answer.
11 ms in 5 seconds what is the acceleration?
It depends on what the initial velocity was. If it was 0, then: 11-0 = 2.2 m/s squared 5
How many seconds does it take to go 30 mph?
Data is insufficient. initial velocity is 0. final velocity is 30 mph. Need acceleration to use the formula v = u + at.
If a car goes in 6.8 seconds how do you figure out the acceleration?
To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.
What is the vehicles velocity after 1.0 seconds?
That depends on its initial velocity and its acceleration. V1 = V0 + a * t
When acceleration occurs?
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
How do you calculate acceleration between 6 and 9 seconds?
To calculate acceleration between 6 and 9 seconds, you need to find the change in velocity during that time interval and then divide it by the time taken. The formula for acceleration is acceleration = (final velocity - initial velocity) / time. Plug in the velocities at 6 seconds and 9 seconds into the formula to get the acceleration.
What is the acceleration of car that increase its speed by 10 milessec after 30 seconds if the initial velocity was 20 milessec?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 20+10 = 30 miles/sec, the initial velocity is 20 miles/sec, and the time is 30 seconds. So, the acceleration of the car is (30 - 20) / 30 = 0.33 miles/sec^2.
Find the acceleration of a car that goes from A meters per second to B meters per second in 8 seconds?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Given the initial velocity (A), final velocity (B), and time (8 seconds), you can substitute the values into the formula to find the acceleration.
An arrow in flight has an initial velocity of 65 meters per second and 10 seconds later it has a velocity of 35 meters per second Which is the acceleration of the arrow?
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
What is the velocity of the ball 0.6 seconds after its release?
Assuming you release it from a position of rest, you must multiply the time by the acceleration. The acceleration due to gravity near Earth's surface is approximately 9.8 meters/second squared.
If acceleration is the change in velocity divided by time calculate the rate of acceleration of the basketball during these 4 seconds?
To calculate the rate of acceleration, you need to know the change in velocity of the basketball over the 4 seconds. If you have the initial and final velocities, you can use the formula: acceleration = (final velocity - initial velocity) / time. For example, if the basketball's initial velocity is 0 m/s and its final velocity is 8 m/s, the acceleration would be (8 m/s - 0 m/s) / 4 s = 2 m/s².
How far does a plane fly in 15 seconds while its velocity is increasing from 75 miles per second to 145 miles per second at a uniform rate of acceleration?
To find the distance traveled, we can use the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. The initial velocity is 75 miles per second, the final velocity is 145 miles per second, and the time is 15 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time. Plug in the values to find the acceleration and then calculate the distance traveled in 15 seconds.
A sprinter explodes out of the starting block with an acceleration pf 2.3 ms2 which she sustains for 1.2 sThenher acceleration drops to zero for the rest of the raceWhat is her velocity at1.2s?
The sprinter's velocity at 1.2 seconds can be calculated using the formula: velocity = initial velocity + acceleration × time. Given the initial velocity is 0 m/s, acceleration is 2.3 m/s^2, and time is 1.2 seconds, the velocity at 1.2 seconds would be 2.76 m/s.
A car accelerates from a standstill to 60 kmhr in 10 seconds What is its acceleration?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Converting the initial velocity of 0 km/hr to m/s and final velocity of 60 km/hr to m/s, and plugging in the values, we get the acceleration to be 2 m/s^2.
