What answer of A car accelerates uniformly from rest after five seconds its final velocity is twenty meter per second its acceleration during third second will be?

So it's acceleration is 4m/s2. So at any point because it says uniformly, it will be accelerating at 4m/s2 each second


What is the speed of a skateboarder who accelerates from rest for 3 seconds down a ramp at an acceleration of 5 mss?

Speed = (initial speed) plus (acceleration) x (time) = 0 + (5) x (3) = 15 meters per second.


What is the average velocity of a car that accelerates from 15 meters per second to 25 meters per second in 10 seconds?

If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)


An eagle accelerates from 15 meters per second to 22 meters per second in 4 seconds. What is the eagle's average acceleration?

Average acceleration is the amount of acceleration per unit of time that a thing or an object undergoes. It is simple to discover. To find the average acceleration, we need only find out how much acceleration occurred and over what period of time. If we have the starting and the ending speeds, then by subtracting them we can find the chane of acceleration. Then we can divide that acceleration by the time it took to occur. The eagle in our example accelerates from 15 m/s to 22 m/s over a period of 4 seconds. His total acceleration was 7 m/s (22 m/s minus 15 m/s = 7 m/s), and, since it took 4 seconds to increase his speed by 7 m/s, the average acceleration is the total acceleration divided by the time it took to happen (as was stated). The average acceleration is 7 m/s divided by 4 seconds or 1.75 meters per second.


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.

A car accelerates to pass a truck going from 20miles per second to 29miles per second in 3 seconds what was the acceleration?

So acceleration is an increase of speed every second. The increase of speed was 9miles/sec and this was over 3 seconds. Therefore there was an acceleration of 3 miles/second every second i.e. 3m/s2
