In this case, speed = time x acceleration. If this happens close to Earth's surface, the acceleration is approximately 9.8 meters/second2.

If an object travels for 15 minutes at a constant velocity of 12 miles per hour west what is its acceleration?
Since acceleration is a change in velocity, if your velocity is constant (does not change), your acceleration is zero.
What is the objects average velocity over a 15 second interval if the object initially at rest experiences an acceleration of 1.7 for 6 sec and travels at that constant velocity for another 9 seconds?
Average velocity is total distance by total time . let us calculate velocity at the end of 6 seconds. v=vo+at v= 0+1.7*6 v=10.2 m/sec distance travelled by object in six seconds x= vot+1/2at2 x=0+.5(1.7)(62) x=30.6 m the final velocity at the end of six seconds that is 10.2m/s will be the initial velocity when objects moves with uniform velocity with a constant velocity x= vot+1/2at2 . . . accel is 0 since velocity is constant between 6 & 15 secs. x=10.2*9=91.8 Again . . average velocity is total distance by total time. Average velocity= [30.6+91.8]/15= 122.4*15 = 8.16m/s
To fully describe the motion of an object you must fully describe its what?
well the main part to this is time. you have to explain the object's acceleration and velocity with reference to time. I'll give you some examples of phrases to use : from t=0 to t=10 the object started from rest and was moving with constant acceleration of 5m/s^2 from t=10 to t=15 the object is moving with constant velocity of 50m/s from t=15 to t=40 the object's velocity decreased with constant retardation (deceleration) of 2m/s^2 until it came to rest again im not sure if all the numbers will add up on that one, juz kinda wrote the figures as i thought of the phrase
What is the final velocity of an object that starts at 45 mph and accelerates at a rate of -10 mphsec for 3 seconds?
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
If your initial velocity was 10 ms-1 right and your final velocity was 5 ms-1 left what is your change in velocity?
The change in velocity is 15 m/s left.

How long does it take an object with a velocity of 2.5 meters a second up to fall 15m?
15 m divided by 2.5 m s-1 is 6 s.

When a storm is moving at 15 kilometers per hour so what do you need to determine it's velocity?
Velocity= a speed and a direction The speed is 15 km/hr You still need a direction to make a velocity.
What is the formula for computing velocity?
The general formula for calculating speed or velocity is given by :- v = s / t [ s divided by t] where v : velocity s : displacement/distance t : time s (displacement) is actually change in the distance, but it can be generalized as just distance traveled. units include : meter, kilometer, miles and other sub types(centimeter, inch) t is the time taken for the object to move the above mentioned distance. units : seconds, hours and other related measures of time. eg : if an object was moved by 15 meters in 3 seconds, its velocity v is given by: v = 15/3 = 5 meters/second or m/s
What is the final velocity of an object that starts at 45 mph and accelerates at a rate of -10 mphsec for 3 seconds?
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
If your initial velocity was 10 ms-1 right and your final velocity was 5 ms-1 left what is your change in velocity?
The change in velocity is 15 m/s left.
