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
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.
What are the units of acceleration?
Acceleration is a change in velocity per unit of time. Velocity is distance (d) per unit of time (t). That makes acceleration distance per unit of time squared, or something like this:We have distance/time2, or d/t2Distance is commonly measured in meters, and time in seconds. This makes acceleration appear in meters per second per second, or meters per second squared, or m/sec2.m/s2meters 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.
You throw a ball straight up with a velocity of 40 meters per second What is the ball's velocity after 5 seconds?
it is 10 meters per second straight down
What is the velocity if travel 5.7 meters per second squared for 4 seconds?
Velocity can be measured in metres per second, not metres per second squared. Acceleration is measured in metres per second squared but knowing only the acceleration does not help in finding the velocity.
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
Why seconds are s2 (squared) in the acceleration formula?
Seconds are not squared in the acceleration formula. The units for acceleration are meters per second squared (m/s^2), where the time unit (seconds) is squared to represent the change in velocity over time.
The si unit of velocity is the meter per second squared true or false?
False. The SI unit of velocity is meters per second (m/s), not meters per second squared. Meters per second squared is the unit for acceleration.
How do you label acceleration?
Acceleration is labeled as "a" and its unit is meters per second squared (m/s^2). It is a vector quantity that represents the rate of change of velocity with respect to time.
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
How do you convert 4.4 miles per hour per second to meters per seconds squared?
To convert 4.4 miles per hour per second to meters per second squared, first convert 4.4 miles to meters (1 mile = 1609.34 meters) and 1 hour to seconds (1 hour = 3600 seconds). Then divide the speed in meters per second by the time in seconds squared to get the acceleration in meters per second squared.

An object is dropped on the earth After 1.5 s what is its speed in meters per second?
The object will be moving at 14.7 meters per second. 1.5 seconds X 9.8 meters per second squared(the gravitational constant). This assumes that the object's original velocity is zero.
What is an accurate statement of acceleration valuea3meters per secondb3meters per second squared c3 squared meters per second d3meters in 3 seconds?
The answer is B - 3 meters per second squared
Why do we measure acceleration in squared seconds as opposed to just seconds?
Acceleration measures the rate of change of velocity over time. The squared seconds unit is used because acceleration is the change in velocity per unit time, so it is expressed as distance per time squared. This allows us to quantify how quickly the velocity of an object is changing over time.
