How far does a car traveling 70 mph go in 3 seconds?
It travels 308 feet every three seconds at 70 mph.
If a car accelerates from 5 m per second to 15 m per second in 2 seconds what is average acceleration of the car?
5 metres per second squared
A car having an initial speed of 16 meters per second is uniformly brought to rest in 4.0 seconds How far does the car travel in this 4.0-second interval?
The answer is 32 meters
What is the speed of someone running 40 yards in 4 seconds?
Their speed is ten yards per second.Takamo added: There are several variables with in this question. We have to determine how fast a person can cover 40 yards. In this case, it's 4 seconds. To determine the actual speed, as in Miles Per Hour, (MPH) we have to use a known constant. Say, a car going 60 MPH. We all know that a car going 60 MPH is traveling at one mile per minute. There are 60 seconds in a minute, and 5280 feet in a mile, so by dividing the 5280 feetby 60 seconds, we find that the car is traveling at a velocity of 88 FPS(feet per second).A human can run, in this case, 40 yards in 4 seconds. There is 120 feet in 40 yards, so the runner moves at a velocity of 30 FPS. To match the un-known, (the MPH of the runner) and compare it to a known MPH, (the car) we divide the FPS of the car by the FPS of the runner and we get 2.6. This is the variable between them, in that the same distance, the car is traveling 2.6 times faster than the runner. Knowing the speed of the car, 60 MPH, and knowing now, how much faster its going than the runner, we simply divide the MPH of the car, 60MPH by 2.6 and we get the runner's land speed of of 23.07 MPH.
What is the acceleration of a car that slows down from 60 ms to 40 m s during a period of 10 seconds?
-2 m/s^2
