Average acceleration = (change in speed) divided by (time for the change) =(15 - 0) / (5) = 15/5 =3 meters per second2
Average acceleration = change in speed/time for the change = 15/5 = 3 meters per second2 .
0 to the nearest hundred, for example.
60 mph = 88 feet per secondThe car's average speed during that 5 seconds is 1/2 of (0 + 88) = 44 feet per second.The distance covered is (average speed) x (time) = 44 x 5 = 220 feet
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).
The car's average speed is 10.64 miles per hour.
A stopped car has a speed of 0 m/s because it is not moving. Speed is the rate at which an object changes its position, so if the car is not changing its position, its speed is 0.
The correct term is velocity, not velocity.There is no reason why an object cannot have 0 velocity and 0 average speed - relative to some fixed reference point. I assume that your school, for example, has 0 velocity and 0 average speed.
Average acceleration = (change in speed) divided by (time for the change) =(15 - 0) / (5) = 15/5 =3 meters per second2
Average acceleration = change in speed/time for the change = 15/5 = 3 meters per second2 .
An average car will go 0-60 in about 8.4 seconds
Put him in sleeper hold and average speed is 0.
0 to the nearest hundred, for example.
speed = distance traveled per unit time. The average speed cannot be obtained without knowing the instantaneous speed sampled over the period of time in question. Let us say you need to calculate the average speed of your car traveling from home to work. You will have to record your instantaneous speed at t=0 (s0), t=1 unit of time (s1), t=2 units of time (s2), ..., t=n units of time (sn). Then the average speed will be (s0+s1+s2+...sn)/n. The smaller the time interval of sampling, the more accurate will be the average. For example, if you only sample at the beginning and the end of your trip, you will say your speed = (0+0)/1 = 0, which is obviously inaccurate. In real life, you trade off accuracy with resources available.
60 mph = 88 feet per secondThe car's average speed during that 5 seconds is 1/2 of (0 + 88) = 44 feet per second.The distance covered is (average speed) x (time) = 44 x 5 = 220 feet
The average velocity is zero as the car returns to its starting point, having no displacement. The average speed, however, is the total distance traveled divided by the total time, which is 2π*200 meters divided by 62.8 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).
