A car traveling at 92 kmh strikes a tree. The front end of the car compresses and the driver comes to rest after traveling 0.85 m. What was the average acceleration of the driver during the collision?

92km/h = 41*5/3*3 =205/9m/s
v = 205/9 m/s
u = 0m/s
s = 0.85m = 85/100m
a = ?
v2 = u2 + 2as
=> 2052/81 = 2 * a * 85/100
=>a = -0.9766m/s2

A car traveling at 25 meters a second speeds up to 40 meters a second over a period of 15 seconds what is the average acceleration of the car?
Average acceleration = (change in speed) divided by (time interval)A = (40 - 25) / 15 = 15/15 = 1 meter/sec2
How do you calculate time with speed and acceleration?
Average acceleration = Change in speed/time so Time = Change in speed/Average acceleration
How do you find average acceleration?
Acceleration = (change in speed) divided by (time for the change)
What is the equation to solve for average acceleration?
AnswerAcceleration = v2 - v1.........................timeAverage Acceleration requires you to average the the initial velocity of your trials and the ending velocity of your trials. You must also find the average for your time trials. Once you achieve these numbers, just plug them into the above formula and you can solve for average acceleration.
An eagle accelerates from 15 meters per second to 22 meters per second in 4 seconds. What is the eagle's average acceleration?
Average acceleration is the amount of acceleration per unit of time that a thing or an object undergoes. It is simple to discover. To find the average acceleration, we need only find out how much acceleration occurred and over what period of time. If we have the starting and the ending speeds, then by subtracting them we can find the chane of acceleration. Then we can divide that acceleration by the time it took to occur. The eagle in our example accelerates from 15 m/s to 22 m/s over a period of 4 seconds. His total acceleration was 7 m/s (22 m/s minus 15 m/s = 7 m/s), and, since it took 4 seconds to increase his speed by 7 m/s, the average acceleration is the total acceleration divided by the time it took to happen (as was stated). The average acceleration is 7 m/s divided by 4 seconds or 1.75 meters per second.

Average acceleration = (change in speed) divided by (time interval)A = (40 - 25) / 15 = 15/15 = 1 meter/sec2
What is the difference between average acceleration and instantaneous acceleration?
Average acceleration is the change in velocity over a specific time interval, while instantaneous acceleration is the acceleration at a specific moment in time. Average acceleration gives an overall picture of how velocity changes over time, while instantaneous acceleration gives the acceleration at a precise point in time.
Equation for average acceleration?
The equation for average acceleration is: average acceleration = change in velocity / change in time.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
No, average acceleration is the overall change in velocity over a specific time interval, whereas instantaneous acceleration is the acceleration at a specific moment in time. For a uniformly accelerated car, the average acceleration is constant over the entire interval, but the instantaneous acceleration can vary at different points during that interval.
Suppose that an object is traveling along a straight line Suppose that its velocity function is given by vt equals 4t2 -8t where t is in seconds Find the objects average acceleration along the time?
The average acceleration of the object over a time interval [a, b] is given by (v(b) - v(a))/(b - a). Given v(t) = 4t^2 - 8t, the average acceleration over the interval [a, b] is (4b^2 - 8b - (4a^2 - 8a))/(b - a).
How do you calculate time with speed and acceleration?
Average acceleration = Change in speed/time so Time = Change in speed/Average acceleration
Find average acceleration and instanious acceleration?
Average acceleration is the change in velocity divided by the change in time over a certain interval. Instantaneous acceleration is the acceleration of an object at a specific moment in time, which can be found by taking the derivative of the velocity function with respect to time.
Average acceleration formula?
Average Acceleration = V/t = Vf-Vi / Tf-Ti
What is the direction of average acceleration?
Average acceleration points in the same direction as the change in velocity over time. If the velocity is increasing, the average acceleration will be in the same direction as the velocity. If the velocity is decreasing, the average acceleration will be in the opposite direction.
A car traveling in a straight line has a velocity of plus 9 point 5 m per s After 3 point 5 s its velocity is plus 9 point 0 m per s What is the car's average acceleration in this time interval?
The car's average acceleration can be calculated using the formula: average acceleration = (final velocity - initial velocity) / time interval. Plugging in the values: (9.0 m/s - 9.5 m/s) / 3.5 s = -0.5 m/s^2. Therefore, the car's average acceleration in this time interval is -0.5 m/s^2.
What is the equation for average speed and acceleration?
Average speed = Distance travelled/time to travel the distance . Average acceleration = Change of speed/time for the change .
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
