A race car starts from rest and accelerates uniformly to a speed of 40 ms in 8.0 seconds how far will the car travel during the 8 seconds
A plane is uniformly accelerated from 60 ms to 80 ms in 12 seconds what is the distance traveled by the plane during this period
((60m/s+80m/s)/2)x12s=840m
A jogger runs at an average speed of 5 ms for 3 minutes then finishes with an average speed of 4 ms for 2 minutes What is his average speed in ms for the run
A speed bike tops a hill at 3.50 ms and accelerates steadily down the hill until reaching a speed of 11.4 ms after 4.20 seconds How far did the bike travel during this period
How far will a driver go by maintaining a constant speed of 70 miles per hour and driving for 6 hours
How long will it take a driver to drive 300 miles by maintaining a constant speed of 60 miles per hour
Time = Distance/Speed = 300 miles/60 mph = 5 hours
Find the uniformed acceleration that causes a car's velocity to increase from 32 ms to 96 ms in a period of 8.0 seconds
The average uninformed acceleration is (delta-V) / (delta-T). Delta-V = (96 - 32) = 64 m/s. Delta-T = 8.0 seconds. A = (64 m/s) / (8.0 sec) = 8 m/s2
A driver traveling at a speed of 21 ms tops a hill and spots a deer standing in the middle of the road 90 meters away He hits the brakes and panic stops the car in 8 seconds How far did the car travel
Assuming that his acceleration was linear (ie. that he slowed
down at a perfectly steady rate), then you can say his velocity at
any point in those eight seconds was:
21 - t(21 / 8) m/s
To get the distance covered in that time, you can simply take
the area under that line between 0 seconds and eight seconds.
Because it's linear, this is very easy. You're dealing with a right
triangle that is 8 seconds wide and 21 meters per second tall. With
a triangle, the area is equal to half it's width times it's height,
so the equation is:
d = 21m/s * 8s / 2
∴d = 168m / 2
∴d = 84m.
So he traveled 84 meters in those 8 seconds, and probably scared
the bejeebers out of that poor deer.
Average speed = 21/2 m/s , Time =8 s, Distance = 8 x 21/2 =
84m
A plane traveling at 80 ms lands on a runway and comes to rest after 10 seconds What was the plane's deceleration
Convert 176 feet second to miles hour
Assuming the question is refering to feet PER second and miles
PER hour,
176 fps = 120 mph
How far does a plane fly in 15 seconds while its velocity is increasing from 75 ms to 145 m s at a uniform rate of acceleration
If it accelerates from 75 m/s to 145 m/s at a uniform rate, then its average speed during
the acceleration is 0.5(145+75) = 110 m/s.
Distance covered in 15 sec at average speed of 110 m/s = (15 x 110) = 1,650 m = 1.65 km.
A motorcycle traveling at 15 m s accelerates at a constant rate of 4.0 ms over a distance of 50 meters What is the final velocity of the motorcycle
Police find skid marks 180 meters long on a highway where a car made an emergency stop Assuming that the deceleration was a equals 10 ms about the maximum for dry pavement how fast was the car t
A pulley system is used to lift a 2000 newton engine up a distance of 3 meters The operator must apply a force of 250 newtons to the chain of the pulley system to lift the motor To lift the engine fi
The trip took 317 days What was the average speed of the sailboat in miles per hour Round to the nearest tenth of a mile hour
We're missing a value, we'll need the distance traveled to
determine that.
You drive a car 2 hours at 40 miles per hour 2 hours at 60 miles per hour how many miles will you travel
If you drive a car at 40 miles per hour for two hours,then the
distance covered will be 80 miles.If you drive the car for another
2 hours at 60 miles per hour ,then you will cover another 120
miles.The total distance you will cover is thus 80 miles + 120
miles = 200 miles.
How many airmiles from Oklahoma city to dallas
Air miles from Oklahoma City, Oklahoma, to Dallas, Texas, total 191 miles. That is 307 kilometers or 166 nautical miles.
What type of measurement is this air pressure in a tire
Air pressure is a measure of how much air is in a tire, or how
much it is inflated. Air pressures are written on apanel on driver
door frame and on tire sidewall. they are very important to tire
wear.
A car traveling at a velocity of 24 m s is accelerated uniformly at a rate of 2 m s for 8 seconds what is the final velocity of the car
Apply to the equation V=U+at . The answer is 40.
