what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
It is 20 seconds.
The average velocity has two parts to it: The average speed and the average direction. The average speed is: (the distance you travel between 0 and 3 seconds) divided by (3). The average direction is: the direction from (the place where you started at 0 seconds) to (the place where you finished at 3 seconds).
14.19 feet per second2 (rounded)
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2
Acceleration = -20 mi/h^2
it's answer "c"
It is 20 seconds.
The average velocity has two parts to it: The average speed and the average direction. The average speed is: (the distance you travel between 0 and 3 seconds) divided by (3). The average direction is: the direction from (the place where you started at 0 seconds) to (the place where you finished at 3 seconds).
To find the average speed between time=0 and time=2, divide the distance traveled by the time (in this case 2 seconds).
14.19 feet per second2 (rounded)
2 meter/seconds squared
From 0-60 in 2.9 seconds.
Acceleration(average) = change in velocity/change in time a = 40 m/s - 0 m/s/2.4 s = 17 m/s2 =======
Since the derivative of velocity is acceleration, the answer would be technically 'no'. Here is why: v = 0 v' = 0 = a Or in variable form... v(x) = x v(0) = 0 v'(0) = 0 = a You can "trick" the derivative into saying that v'(x) = 1 = a (since the derivative of x = 1) and then stating v'(0) = 1 = a... but that is not entirely correct. Acceleration is a change over time and is measured at more then one point (i.e. the acceleration of this body of matter is y from time 1 to 5) unless using derivatives to form the equation of the acceleration line/curve. If an object has a constant acceleration of 1, then the velocity is constantly increasing over that time. Using the equation discussed above and looking at acceleration over time, at 0 seconds, acceleration is 0 and so is velocity, but from 0-1 seconds acceleration is 1 and velocity is 1 as well. 0-2 seconds, acceleration is 1, but velocity would be 2 (at the end of 2 seconds).
Not sure of your abbreviations. I'll assume that 'ms' = "meters per second", and 's' = "seconds" Change in speed = (25 - 0) = 25 meters per second Time = 8 seconds Average acceleration = (change in speed) / (time) = 25/8 = 3.125 meters per second2
An F1 car can reach up to 350kph during a race. 0-60 in 2-2.5 seconds.
