What is the unit rate for 840 feet in 40 seconds?
840 feet/40 seconds = 21 feet per second.840 feet/40 seconds = 21 feet per second.840 feet/40 seconds = 21 feet per second.840 feet/40 seconds = 21 feet per second.
What is the average acceleration of a care that goes from rest to 60 mph in 7 seconds in feet per second?
the car goes from 0 miles in an hour to 60 miles in an hour over 7 seconds this can be changed to minuets (60 minuets in an hour) the car goes from 0 miles in a minuet to 1 mile in a minuet over 7 seconds this can be changed to seconds (60 seconds in a minuet) the car goes from 0 miles in a second to 1/60 miles in a minuet over 7 seconds which then can be changed to feet (5280 feet in a mile) the car goes from 0 feet in a second to 5280/60 feet in a second over 7 seconds this can be simplified the car goes from 0 feet in a second to 88 feet in a second over 7 seconds now lets divide everything by 7 the car goes from 0 feet in a second to 12.57 feet in a second over 1 seconds so are answer is... the car accelerate from 0 to 12.57 feet per second in 1 second
What is the speed of 2g?
It depends on the area or city you live, the average speed of the 2g network is around 160 kbps and it varies during peak hours (7.00 am to 11.00 pm)
A stone falls from rest how fast is it falling after 10 seconds?
Speed = (acceleration) times (time)Acceleration = gravity = 9.8 meters (32.2 feet) per second2Speed = 10g = 98 meters (322 feet) per second
What is speed of object at 3 seconds given an acceleration of 16 feet per second squared for 3 seconds?
I assume the object starts from rest. The speed will be 16*3 which is 48m/s
If a train is traveling at 50 feet per second and experiences an acceleration of 10 feet per second how many seconds will it take to stop?
Well if it accelerates, it speeds up so it won't stop. If you mean decelarate, it decreases 10 ft/s every second, so 50/10 is 5 seconds
A train travels 20 feet in 0.5 second. At this same speed how many feet will it travel in 3 seconds?
20 feet in 0,5 seconds ==> 40 feet per second 40 feet per second * 3 seconds = 120 feet
You are running at the rate of 24 feet per second in a 40 yard dash it take you 4 seconds to slow to a stop what is your acceleration?
-6 ft/sec2
What is the speed of an object in free fall 2 seconds after falling from rest?
Acceleration of gravity near the surface of the earth is 9.8 meters (32.2 feet) per second2. Downward velocity after 2 seconds = 19.2 meters (64.4 feet) per second.
What does per second per second mean?
Per second per second or (/s/s) refers to the rate of acceleration. If you are standing still and you increase your speed at a rate of 5 feet per second per second that means after 1 second you'll be moving at 5 feet per second, after two seconds you'll be moving at 10 feet per second, after three seconds you'll be moving at 15 feet per second, and so on. Every second that goes by, 5 more feet per second will be added to your speed. So 5ft/s/s is a rate of acceleration. An easier example to understand, instead of per second per second, is per hour per second. If you are in a car that is standing still and you increase your speed at a rate of 5 miles per hour per second that means after 1 second you'll be traveling at 5 miles per hour. After 2 seconds your speed will have reached 10 mph. After 10 seconds you'll be traveling at 50mph. Each second that goes by you add 5mph to the speed.
What is 400 feet in 52.4 seconds?
In order to translate feet and seconds into feet per second, all you have to do is divide the number of feet by the number of seconds. In this case, the answer is 7.634 ft/s
A track runner ran 315 feet in nine seconds what was his average speed in feet per second?
315 feet in 9 seconds = about 35 feet per second.
