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.
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 object's instantaneous acceleration is (8t - 8) at any time.We can't calculate the average acceleration, because you haven't defined a periodof time over which to average it. We need the start and finish times in order tofind an average.
Find average acceleration and instanious acceleration?
average acceleration is the average of the acceleration of a body in its entire motion where as instantaneous acceleration is the rate of change of velocity at an instant. it may be a function of time or velocity or displacement.
What is the difference between average acceleration and instantaneous acceleration?
Average acceleration is the average of the accelerations acquired in the whole journey by a body while instantaneous acceleration is the acceleration of the body at any particular instant of time.
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
Derive the equation for instantaneous average acceleration vector?
You have a contradiction in your question. Instantaneous acceleration is the acceleration at a certain moment in time. Average acceleration is the average over a time interval.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
How do you calculate time with speed and acceleration?
Average acceleration = Change in speed/time so Time = Change in speed/Average acceleration
Average acceleration formula?
Average Acceleration = V/t = Vf-Vi / Tf-Ti
What is an example of average acceleration?
All acceleration in real life is an average figure = velocity increase / time
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 .
How do you find average acceleration?
Acceleration = (change in speed) divided by (time for the change)
