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.

What is the acceleration of a ball that is traveling at a constant velocity of 50 meters per second and has been traveling for 2 minutes?
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.
What is the acceleration of a ball that is traveling at a constant velocity of fifty miles and has been traveling for over 2 minutes?
If an object is traveling at a constant velocity, its acceleration is 0. Even if it traveled for 2 years.
If the speed of an object changes from 121 minutes per second to 98 minutes per second during a time interval of 12 seconds what is the acceleration of the object?
b. -1.92 m/s2Minutes per second is not a unit of velocity. If the question meant meters per second, the answer is correct.
You drove 10 miles to school in 20 minutes Then drove the 10 miles home in 30 minutes your average velocity was?
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.
A train starting from rest attains a velocity of 72Km hr in 5 minutes. Assuming that the acceleration is uniform what is the distance travel by train while attained the velocity?
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
What is the difference between constant velocity and average velocity?
Constant velocity means the object is moving at a consistent speed in a straight line with no change in direction. Average velocity, on the other hand, takes into account changes in velocity over a given time interval and is calculated as the total displacement divided by the total time elapsed.
The velocity of a body was noted to be constant during five minutes of its motion What was its acceleration during this interval?
The acceleration of the body was zero during this interval because its velocity was constant. Acceleration is the rate of change of velocity, so if the velocity does not change, the acceleration is zero.
If an object travels for 15 minutes at a constant velocity of 12 miles per hour west what is its acceleration?
The acceleration is zero since the object is moving at a constant velocity. Acceleration is the rate of change of velocity, and in this case, the velocity is not changing.
What would be the acceleration of a object that is moving with a constant velocity of 0.25 minutes to the right?
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
When a ball is traveling at a constant velocity of 50 ms and has been traveling for over 2 minutes what is the balls acceleration?
If the ball is traveling at a constant velocity of 50 m/s, then its acceleration is 0 m/s^2. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity, and therefore no acceleration.

A student walks 0.85 km to class in 5 minutes and then back in 7.1 minutes What is his average velocity?
The total displacement is 0 km, as the student returns to the starting point. The total time taken is 5 minutes + 7.1 minutes = 12.1 minutes. Therefore, the average velocity is 0 km divided by 12.1 minutes, which equals 0 km/min.

What is the differens between average velocity and instant velocity?
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!
How A speed boat moving at a velocity of 25 ms runs out of gas and drifts to a stop 3 minutes later 100 meters away. What is its rate of deceleration?
To find the rate of deceleration, we first need to convert the time from minutes to seconds. 3 minutes = 180 seconds. Next, we use the equation of motion: final velocity^2 = initial velocity^2 + 2 * acceleration * distance. Since the boat comes to a stop, the final velocity is 0 m/s. Substituting the values and solving for acceleration, we get a deceleration rate of 0.139 m/s^2.
What is the average velocity in mph of 2.5 miles ran in 15 minutes?
Average speed = Distance/Time = 2.5 miles/15 minutes = 10 miles per hour
