What else can I help you with?
An object's velocity changes from 30 meters per second to 23 meters per second in 3 seconds What is is its acceleration?
-2.33 metres per second squared
If a trucks brakes are applied for 2 seconds giving it acceleration of -3.1 ms2 what will the trucks new speed be in ms?
No starting velocity was given, so I can't give a correct answer, but I can answer part of the question. Given an acceleration and a time through which an object accelerates, you can determine the change in velocity. Acceleration is just the change of velocity over a period of time. Since we have an acceleration of -3.1 meters per second squared, acting for two seconds, we have a change in velocity of -6.2 meters per second. Take the original velocity and subtract 6.2 meters per second to get the answer.
What is the velocity of this object after 30 seconds with an acceleration of 7.8 meters per second squared?
IF it started out from rest, then V = a t = (7.8 x 30) = 234 meters per secondin the direction of the acceleration, at the end of 30 seconds.
An object traveling at a constant 20 miles per second in a circular path is changing what?
This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.
An arrow in flight has an initial velocity of 65 meters per second and 10 seconds later it has a velocity of 35 meters per second Which is the acceleration of the arrow?
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
What is the velocity of the moving object at time 5 second?
To determine the velocity of a moving object at a specific time, you would need the object's position function or acceleration function. If you have the position function, you can differentiate it to get the velocity function and then substitute t=5 seconds. If you have the acceleration function, integrate it with respect to time to get the velocity function and then substitute t=5 seconds.
What is the acceleration of an object that takes 7 seconds to change its velocity from 25miles per second to 39miles per second?
2 miles per second squared
How are veloc ty and acceleration related?
Velocity and acceleration are related in that acceleration is the rate of change of velocity over time. If an object is accelerating, its velocity is changing. A positive acceleration means the object is speeding up, while a negative acceleration means the object is slowing down.
An object's velocity changes from 30 meters per second to 23 meters per second in 3 seconds What is is its acceleration?
-2.33 metres per second squared
An object moving at 30 miles per ssecond takes 5 s to come to a stop what is the object's acceleration?
The object's acceleration is equal to the change in velocity divided by the time taken. The initial velocity is 30 miles per second, and the final velocity is 0 miles per second. The change in velocity is 30 miles per second. Therefore, the acceleration is 30 miles per second divided by 5 seconds, which is 6 miles per second squared.
Why do we measure acceleration in squared seconds as opposed to just seconds?
Speed, or velocity, is measured in distance per second; it is the rate of change of distance with time.Acceleration is the rate of change of velocity with time, or distance per second per second, which is distance per seconds squared,
What is the acceleration of an object that starts stopped and after 5 seconds is going 25mm per hour?
the acceleration is increasing speed Acceleration = velocity change / time velocity change = 0 to 25 mm/hr = 25 mm/hr time = 5 seconds therefore acceleration = 25/5 mm/hr per second = 5 mm per hour per second.
If object moves with constant acceleration its velocity is?
It velocity is constantly increasing, v=vo + at.
An object with constant velocity has positive acceleration?
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.
