How far can the average person walk in 15 seconds?
If you walk quickly but do not run you can average 6 feet per second or 15 x 6 = 90 feet in 15 seconds ( home plate to first base)
If a submarine dives 378 ft in 14 seconds the average change in elevation is feet per second?
27 fps
If distance is 50 meters and time is 5 seconds what is the speed?
If an object moves 50 meters in 5 seconds, its average speed is 50/5 = 10 meters per second.
How long does it take to stop from 65 mph?
You need to know one other thing to answer this question. The acceleration of the braking. The formula is: t=v/a where t is the time, a is the acceleration and v is velocity. For example, in a regular car, to stop from 65 mph (95.3 ft/sec) at a deceleration of 1G (32 feet per second²) would take 2.98 seconds. Incidentally, it would take 142 feet to stop ( formula s=½at² where s is distance).I assumed you are asking this as it relates to a car. 1G is a very good average braking acceleration for a car.
How long would it take to fall 6000 ft?
Well, roughly, it depends on weight, but not at first. Initially you fall at the acceleration of gravity at 32 feet per second per second. Velocity is acceleration x time and you reach a terminal velocity of about 110 mph depending on weight, or about 160 feet per second. Thus it takes 160/32= 5 seconds to reach that speed; then the sped is constant due to (drag) at 160 feet per second. You would have traveled s = 1/2 accel x time squared = 32/2 x 5x5 = 400 feet. You have 5600 feet to go and s = vt = 5600; t = 5600/160 = 35 seconds. Total time is 35 + 5 = 40 seconds
A car accelerates from 4 meters/second to 16 meters/second in 4 seconds. The car’s acceleration is blankmeters/second2?
The acceleration of the body is 3 m/s²
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.
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!)
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
When a runner accelerates from 0 miles per second to 3 miles per second in 12 seconds what was the acceleration?
3 / 12 = 0.25 miles/second2.
A car accelerates to pass a truck going from 20 meters per second to 29 meters per second in 3 seconds What is the acceleration?
3 m/s2
A car driving on the turnpike accelerates uniformly from 91.0ft per second to 118ft per second in 3.20 seconds. what is the cars acceleration?
8.44 ft/s^2
What is the average acceleration of a car that goes from rest to 60 mph in 8 seconds?
The car accelerates an average of 7.5 mph per second. It increases its speed 7.5 mph for every second that it accelerates. The car accelerated from zero to 60 mph in 8 seconds. If we wish to find out how fast it accelerated, we need to divide its acceleration (final speed minus initial speed) by the amount of time that it took to get going that fast. In this case, 60 divided by 8 equals the answer 7.5 mph/sec.
How many meters does a car travel that starts from rest and accelerates for 4.7 seconds with an acceleration rate of 3.6 meters per second squared?
60.912 meters in that time
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 was the finally velocity of a car that was traveling at 4ms and accelerated 2ms for seconds?
The question does not specify how many seconds it accelerates for so I would suggest that the answer is 300,000 km per second (approx).The question does not specify how many seconds it accelerates for so I would suggest that the answer is 300,000 km per second (approx).The question does not specify how many seconds it accelerates for so I would suggest that the answer is 300,000 km per second (approx).The question does not specify how many seconds it accelerates for so I would suggest that the answer is 300,000 km per second (approx).
