Average Velocity = change in position/change in time

V = 35.2 m - 0 m/6.7 s - 0 s

4.8 m/s

Q: What is the average velocity of an object that begins at 0 m and travels for 6.7 seconds in the positive direction for 35.2 m?

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 velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.

0.0002315 m/s OR 0.0008333 km/hour The velocity of an object is the rate of its change in position in a certain direction. Velocity is a vector quantity; this means that it has both a magnitude and direction. To find the average velocity of an object in motion, the following equation is used: average velocity= (total displacement)/ (total time elapsed) The SI units of velocity are "m/s" , but any distance unit over any time unit is also acceptable. Solving for the velocity asked for: First let's change hours to seconds: (12 hours ) x (6o minutes/hour )x (60 seconds/minute)= 43200 seconds Finding the velocity: average velocity= (displacement)/ (time)= 10m/ 43200 seconds= 0.000231481 m/s

The object's average speed during that time is (the distance it covered) divided by (14.1).You can't tell its velocity, unless you know something about the direction in which it moved.

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)

Without knowing some of the conditions that led up to the situation at 9 seconds, I'm afraid there's no way to figure that out. By the way, once you know the 'velocity', you know the 'direction'. 'Velocity' means speed and direction. It's not just a big technical-sounding word for 'speed'.

A car in the middle of the intersection, 3 seconds after the light turned green.

Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.

There is no answer to your question without knowing the direction of the velocity and of the force application.

Positive acceleration occurs when an object is speeding up in the positive direction, meaning its velocity is increasing over time. This could be due to a force pushing the object in the positive direction, resulting in a positive rate of change of velocity.

No. The direction changes all the time.
