Magnitude of average acceleration = (change of speed) divided by (time for the change)
Average 'A' = (16 - 6) / 240 seconds = 10/240 = 1/24 meter per second2
-- That's the average over the 4 minutes. We don't know anything about the
value of the acceleration at any particular instant during the 4 minutes..
-- We're working entirely with scalars ... speed, not velocity, and magnitude of
acceleration ... since we don't know anything about the car's direction at any
point in time during the whole event.
zero - it is constat velocity. so acceleration is zero50 m/s2 Another : The acceleration is ZERO. Acceleration is defined as the change in velocity per unit time. If the ball is traveling a constant velocity over a two minute period, the acceleration would be zero since there is no change in velocity.
If an object is traveling at a constant velocity, its acceleration is 0. Even if it traveled for 2 years.
b. -1.92 m/s2Minutes per second is not a unit of velocity. If the question meant meters per second, the answer is correct.
Velocity = Distance ÷ Time Average Velocity = (10 + 10) ÷ (1/3 + 1/2) = 20 ÷ 5/6 = 20 x 6/5 = 24 mph NOTE : The times in minutes have been converted into fractions of an hour to enable the answer to be provided in miles per hour.
As the acceleration is uniform, the train has an average speed that is half the difference between the start and final velocities, which in this case is half the final velocity. 1 hr = 60 min 1 km/h = 1 km ÷ 1 hr = km ÷ 60 min = 1/60 km/min Distance = velocity × time = (½ × 72 × 1/60 km/min) × (5 min) = 36/60 × 5 km = 3 km
The average velocity is trying to find how fast the car is going at an average rate. However, constant velocity means that the car is going at an unchanged velocity. Say a car is going at 75 m/s and then changes to 50 m/s and then changes to 25 m/s in 30 minutes. The car is going at different velocities at different times. To find the average, you simply just add the 3 together, then divide by 3 giving you, 50 m/s In the 30 minutes, it's average velocity was 50 m/s However, for a car going at a constant velocity, it means that the velocity never changes. Say a car is going at a constant velocity for 30 minutes at 50 m/s. In those 30 minutes, the car will never change it's velocity and remain at 50 m/s. Constant means that it doesn't change.
Acceleration means speeding up or slowing down, a change in velocity. Since the velocity was constant, the acceleration was. 0
1). If neither speed nor direction are changing, then acceleration is zero.2). "minutes" is not a unit of velocity, but we get the idea
Since acceleration is a change in velocity, if your velocity is constant (does not change), your acceleration is zero.

If the ball is traveling a constant velocity over a two minute period, the acceleration would be zero since there is no change in velocity.
When something is traveling at a constant velocity it has no acceleration. In other words your answer is 0.
If an object is traveling at a constant velocity, its acceleration is 0. Even if it traveled for 2 years.
b. -1.92 m/s2Minutes per second is not a unit of velocity. If the question meant meters per second, the answer is correct.
Since average velocity is total displacement over total time, the answer is 0m/s, because there is no displacement. (Remember, velocity has a direction unlike speed).
Think of average velocity as "overall" velocity. For example, if I walk down the block (let's say it's a distance of 100 meters), and it takes me 5 minutes, my AVERAGE velocity is just:v_ave = Δx/Δtwhere Δx is the change in position and Δt is the elapsed time.v_ave = (100 m) / (5 min)v_ave = (100 m) / (300 sec)v_ave = (1/3) m/sBut instantaneous velocity is a different concept: let's say for a while I walked, then I jogged, then I stopped, then I sprinted, then I walked. The overall trip still ended up taking me 5 minutes, so my average velocity is just as I've calculated it above, but my INSTANTANEOUS velocity changes as I change speeds at any given time in between.Hope this helps!
Average speed = Distance/Time = 2.5 miles/15 minutes = 10 miles per hour
There is not an overall measurement, just time is measured in seconds or minutes on the x-axis and velosity on the y-axis however velocity x time is acceleration which is measured in m/s2
