A person is traveling at 20 miles per second in a car when the car hits a tree the person comes to a complete stop in 0.4 seconds what was the person's acceleration?

Acceleration = (change in speed) / (time for the change) = (0 - 20)/0.4 = -50 miles/second2
That rate of acceleration is roughly 8,200 G's, which I'm sure the passenger
would undoubtedly notice, and would not enjoy one bit. And if you think that
HE would be bent out of shape, you should not even LOOK at the tree!
The reason for that ridiculous number is the fact that before he hits the tree,
you've got him going at roughly Mach 93.8 ! ("20 miles per second")

What is the acceleration of a car traveling from 0 to 60 miles in 4 seconds?
There is no acceleration if the car is travelling at a steady 54,000 miles per hour.
Dave is traveling at 20 meters per second in a car when the car hits a tree so Dave comes to a complete stop in point 4 seconds so what is Dave's acceleration?
His acceleration is minus fifty m/s/s, or ~ 5.5g.Highly survivable if he is wearing his seat belt.
What is the acceleration of a sprinter that runs a race in 12 seconds and finishes the race traveling 24 meters per second?
The sprinter's acceleration is 2 meters per second squared.
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
A 1500 kg car takes 2 point 5 seconds to come to a complete stop after traveling 25m per s calculate the force that is required?
Solve this in two steps. First, find the acceleration as (difference of speed) / time. Second, use Newton's Second Law to find the force (F=ma, that is, force = mass x acceleration).

What is the acceleration of a car traveling 1.2 meters long in 2 seconds?
1.2 divided by 2 seconds equals .6m/s... i think. acceleration without speeding is when you're going in circles, but you feel like you're going faster.
If starting on a skateboard and 10 seconds later traveling 20miles per second what is acceleration?
20 miles per second / 10 seconds = 2 miles per second ^ 2
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 and magnitude of 32.5 kg object that travels 100m in 10 seconds?
You can't calculate the acceleration from the information provided. The object may be traveling at constant velocity, in which case the acceleration is zero; or it may start slowly end end up faster, or vice versa, in which case the acceleration will be non-zero.

What is the acceleration in miles per second squared if a car is traveling 20 miles per second and takes 3 seconds to brake?
-6.667 miles per second squared

If an object is droppes how fast is it traveling after 1 seconds?
In freefall, an object's velocity at a certain time can be calculated using the equation v(t)=a*t Where a=acceleration. On Earth's surface, acceleration due to gravity is equal to 9.8 m/s^2
A car traveling at speed 30 meters per second and stops a break at 3.0 seconds what is the acceleration?
Just divide the speed difference by the time - a difference of 30 m/s, divided by 3 seconds, is equal to 10 m/s2.
