Magnitude of acceleration = (change in speed) / (time for the change) = 2/5
Acceleration = 0.4 meters per second2 north
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 change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
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.
(change in velocity)/(change in time)=avg. acceleration (-30 m/s)/(15s)= -2 m/s2
If velocity is steady and doesn't change, then there is 0 acceleration.
The magnitude of the acceleration of the car is zero. This is because acceleration is the rate of change of velocity, and since the car is traveling with a constant velocity along the east, there is no change in velocity and therefore no acceleration.
To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.

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.
To calculate acceleration between 6 and 9 seconds, you need to find the change in velocity during that time interval and then divide it by the time taken. The formula for acceleration is acceleration = (final velocity - initial velocity) / time. Plug in the velocities at 6 seconds and 9 seconds into the formula to get the acceleration.
The acceleration from 0 to 2s is the rate of change of velocity over that time interval. It can be calculated by dividing the change in velocity by the time taken. Mathematically, a = (v_final - v_initial) / t.
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)
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.
Speed is a measure of how fast an object is moving, velocity includes both speed and direction, while acceleration is the rate at which an object's velocity is changing. In simple terms, velocity determines how fast an object is moving in a specific direction, while acceleration measures how quickly the velocity is changing.

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
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.
