if the velocity is constant, the acceleration is zero. The acceleration is the rate at which the velocity changes, so if it stays the same, the car isn't accelerating.
The time it takes to execute this maneuver is [ 200 / (average of 40 and 80) ] = [ 3 and 1/3 ] seconds.Acceleration = (change in speed) / (time for the change)= 20/(3 and 1/3) = 20/(10/3) = 20 x (3/10) = 60/10 = 6 meters/sec2 = about 0.61 G
(80 miles)/(2 hours) = 40 miles/hour.

twice 40 goes into 80 twice so it goes into 90 twice with 10 left over.
The acceleration of the car is 0.5 m/s^2. This is calculated by dividing the change in velocity (40 m/s) by the time taken (80 seconds).
The acceleration of the car can be calculated using the formula: acceleration = (change in velocity) / time. In this case, the change in velocity is 40 m/s and the time is 80 seconds. Therefore, acceleration = 40 m/s / 80 s = 0.5 m/s². So, the correct answer is A. 0.5 m/s².
First, convert the speeds to SI units, that is, to meters/second. Then, simply subtract the difference in speed by the 2 seconds. The result will be in meters/sec2.
well 40 miles per hour means that a car goes 40 miles in one hour... so if a car is going 80 miles in one hour and you divide the 80 and one hour by 2.. then you get 40 miles in 30 minures.. and the car is going 80 miles per hour.
2 goes into 80 .....40 times
To find the acceleration, we first need to calculate the change in velocity. The car decelerates from 80 km/h to 20 km/h, giving a change of ( 20 - 80 = -60 ) km/h. The time taken for this change is 0.5 hours. Acceleration is calculated as the change in velocity divided by the time: [ \text{Acceleration} = \frac{-60 \text{ km/h}}{0.5 \text{ h}} = -120 \text{ km/h}^2. ] Thus, the acceleration is -120 km/h².
Oh, dude, like, 40 goes into 80, um, two times. It's like basic math, you know? You just divide 80 by 40 and bam, you got your answer. Math can be easy when you just chill and think about it for a sec.

1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
(80 miles)/(2 hours) = 40 miles/hour.
