We don't actually need to know the stopping distance. All we need is 75 mph in 2 seconds.
Acceleration is defined as (change in speed) divided by (time for the change). We have both
of those numbers, so we can immediately write a perfectly good expression for acceleration:
Acceleration = (-75 / 2) miles per hour per second.
The 'dimensions' are correct ... (length) / (time)2. All we have to do is massage it to obtain
the proper units.
(-75 mi/hr) x (1 hr/3,600 sec) x (1609.344 meter/mile) / (2 sec) =
(-75 x 1609.344) / (2 x 3,600) (mile - hour - meter / hour - second - second - mile) =
- 16.764 meters/second2(rounded)

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.
What is the speed of a plane traveling 395000 meters in 9000 seconds?
395000 meters/9000 seconds is 43.889 meters/second
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
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
If a car is traveling 100 meters in 1400 seconds how fast is it traveling?
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.

To pass a truck a car initially traveling 25 meters per second accelerates at a constant rate of 3 meters per second squared after 6 seconds how fast is the car traveling?
That's easy, if the car is initially traveling at 25 meters per second and gradually accelerates 3 meters per second for 6 seconds then the car is traveling at 43 meters per second.
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

A car accelerates from 4 meters/second to 16 meters/second in 4 seconds. The car’s acceleration is blankmeters/second2?
The acceleration of the body is 3 m/s²
What is the acceleration of 3 meters per second to 9 meters per second in 3 seconds?
acceleration = change in velocity divided by timeaccel = (9-3)/3 = 6/3 = 2 meters per second per second
Ignoring the effects of air resistance what is the speed in of the object after falling 3 seconds?
Assuming (1) the object starts from rest, (2) air resistance is insignificant, the object speeds up by about 9.8 meters/second every second. That's the strength of the gravitational field. Just multiply this acceleration (9.8 meters/second2) by the time.
How much does its speed change after 5 minutes with an acceleration of 470 meters per second?
"470 meters per second" is a speed, not an acceleration. Assuming you mean "470 meters per second square", that is the same as a change of 470 meters per second every second. Just multiply by the number of seconds to get the change in speed."470 meters per second" is a speed, not an acceleration.
