A car traveling at 8 meters per second due north speeds up to 10 meters per second in the same direction If it takes the car 5 seconds to change its velocity what is the car's acceleration?

Magnitude of acceleration = (change in speed) / (time for the change) = 2/5
Acceleration = 0.4 meters per second2 north

What is the acceleration of a car that maintains a constant velocity of 100km per h for 10 seconds?
Acceleration is the time rate of change of velocity. If velocity is constant, then acceleration is zero. Note: "100 km per h for 10 seconds" is a constant speed, but not necessarily a constant velocity, since we're told nothing about the direction. If the car moves in a perfectly straight line during those 10 seconds, then its velocity is constant. If it makes a curve, then its velocity is not constant even though its speed is, and there is acceleration.
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 is the average acceleration between 0 seconds and 4 seconds?
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)
If a car traveling at 30meters per second slows to a stop in 15 seconds what was the cars acceleration?
(change in velocity)/(change in time)=avg. acceleration (-30 m/s)/(15s)= -2 m/s2
What is the acceleration of a car with a steady velocity of 100 km per hour for 100 seconds?
If velocity is steady and doesn't change, then there is 0 acceleration.

What is the magnitude of the acceleration of the car who is traveling along east with a constant velocity?
acceleration is the change in velocity by change in time (often meters/second/second). so, if a car was travelling 10m/s and ten seconds later, it is travelling 20m/s in the same direction, the acceleration would be (20m/s-10m/s)/10s=1m/s/s. with a constant velocity the change in velocity is zero (x m/s - x m/s)/y s=0m/s/s and acceleration is also zero.
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.
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)
Can bodies with different velocities have same acceleration?
Yes, velocity is acceleration x time. If acceleration is the same, velocity can be different as it changes with time. For example a car accelerating with constant acceleration will have a different velocity after 5 seconds than it will have at 2 seconds.
How the terms speed velocity and acceleration are related to each other?
Speed is the rate of motion usually expressed as distance traveled per unit of time.Velocity is the rate of change of position. Both speed and direction are required. Acceleration is the rate of change in velocity. In common speech, acceleration is only for an increase in speed; a decrease in speed is deceleration. In physics, any increase or decrease in speed or change of direction is referred to as acceleration.

What is5 th grade formula fir acceleration?
The rate of change of velocity in a particular direction per unit second is acceleration. Let us assume a body is moving at a speed v' in particular direction, say north, and in t seconds, its velocity increases/decreases to v". So the acceleration is, a=(v"~v')/t
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 is the average acceleration between 0 seconds and 4 seconds?
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)
If a car goes in 6.8 seconds how do you figure out the acceleration?
Acceleration= distance / velocity squared
What is the acceleration of a car that moves at a steady velocity of 100 kilometers per hour for 100 seconds?
If the car doesn't change direction during that 100 seconds, then it's zero. If the car's direction changes, then the acceleration isn't zero, but the question doesn't give any information from which to evaluate it.
If a car traveling at 30meters per second slows to a stop in 15 seconds what was the cars acceleration?
(change in velocity)/(change in time)=avg. acceleration (-30 m/s)/(15s)= -2 m/s2
