What else can I help you with?
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 acceleration experienced by a car that takes 10 seconds to reach 27 meters per seconds from rest?
velocity = acceleration x time 27 = acceleration x 10 acceleration = 2.7 m/sec/sec
If velocity is measured in kilometers per hour and time is measured in hours the unit of acceleration is?
Kilometers/hour2. Note that for this kind of calculation, it is much more common to measure distances in meters, time in seconds, velocity in meters/second, and acceleration in meters/second2.
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.
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.
When acceleration occurs?
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
Find the acceleration of a car that goes from A meters per second to B meters per second in 8 seconds?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Given the initial velocity (A), final velocity (B), and time (8 seconds), you can substitute the values into the formula to find the 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
If an aircraft on its take-off run has a steady acceleration of 3 meters per second squared what velocity does the aircraft gain in 4 seconds?
The velocity gained by the aircraft in 4 seconds can be calculated using the formula: velocity = acceleration × time. Given acceleration of 3 m/s^2 and time of 4 seconds, the velocity gained by the aircraft would be 12 meters per second.
What is the acceleration experienced by a car that takes 10 seconds to reach 27 meters per seconds from rest?
velocity = acceleration x time 27 = acceleration x 10 acceleration = 2.7 m/sec/sec
If velocity is measured in kilometers per hour and time is measured in hours the unit of acceleration is?
Kilometers/hour2. Note that for this kind of calculation, it is much more common to measure distances in meters, time in seconds, velocity in meters/second, and acceleration in meters/second2.
What is the velocity of the ball 0.6 seconds after its release?
Assuming you release it from a position of rest, you must multiply the time by the acceleration. The acceleration due to gravity near Earth's surface is approximately 9.8 meters/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.
How do you derive units for acceleration?
Acceleration is the rate of change of velocity over time. By dividing a unit of velocity by a unit of time, we can derive the unit of acceleration. For example, if velocity is measured in meters per second (m/s) and time is measured in seconds (s), acceleration would be in meters per second squared (m/s^2).
HOW UNIT OF ACCELERATION WAS DERIVED?
The unit of acceleration, meters per second squared (m/s²), is derived from the definition of acceleration itself, which is the rate of change of velocity over time. Velocity is measured in meters per second (m/s), and since acceleration represents how much velocity changes per second, we divide velocity by time. Hence, when we express acceleration in terms of its fundamental dimensions, we get meters per second (velocity) divided by seconds (time), resulting in m/s².

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.
