∙ 14y agoThe car's speed after 5 seconds can be calculated using the formula ( v = u + at ), where (v) is the final velocity, (u) is the initial velocity (0 m/s in this case), (a) is the acceleration (6 m/s(^2)), and (t) is the time (5 seconds). Plugging in the values gives (v = 0 + 6 \times 5 = 30 ) m/s. Thus, the car will be going 30 m/s after 5 seconds.
The formula for distance traveled with uniformly accelerated motion is d = 0.5 * a * t^2, where d is the distance, a is the acceleration, and t is the time. Plugging in the values: d = 0.5 * 40 * 8^2 = 0.5 * 40 * 64 = 1280 meters. Therefore, the car will travel 1280 meters in 8 seconds.
Sydney's car accelerates at 5.9 m/s^2, while Sean's car accelerates at 3.6 m/s^2. Sean starting 1.0 second early gives him an initial distance advantage, but Sydney's higher acceleration rate means she will catch up and overtake Sean at some point during the race. The exact point of overtaking can be calculated by comparing their positions over time.
Some examples of things that are fast include cheetahs, race cars, and high-speed trains.
When something is said to be very fast, it means that it is quick or rapid or swift. Something that is said to be very fast is time passing when you are enjoying your self. If "Very fast" is said by a timekeeper at the end of a race I'd just run, I'd say "How fast?"
Do the work at your own pace and don't try to rush.
30m/s
On average you will be going around 18.75mph
14.4km/hr or 9miles/hr
160 m
You are running 23.31 miles per hour.
You have averaged 36.5 miles per hour. You are probably going quite a bit faster than that at the end.
100 meters/15.2 seconds 100 meters = 0.0621371192 miles 15.2 seconds = 0.00422222222 hours 100 m/15.2s = 14.7166861 mph average
quarter-mile drag race in under 10 seconds
It is a fairly anaerobic race due to the fast speed you are going at the hole time. I guess you could say the first 200m are aerobic because you are getting into the race, but you are going so fast (if your good enough) to have it be all run without oxygen.
30 m/sUse the kinematic equation:vf=vi+at,where:vf is the final velocity, vi is the initial velocity, a is the rate of acceleration, and t is the time interval.Knownvi = 0 m/sa = 6 m/s2 = 6 m/s/st = 5 sUnknownvfSolutionPlug in the known values and solve.#vf = 0 + 6 m/s/s x 5s = 30 m/s
he completes it in 69.9 seconds
To win a race in two seconds would depend on the type of race that you are running. If the race is to see who goes the farthest in two seconds then it is possible to win.
