What is the acceleration of a driver that starts his car and within 5 seconds reaches a velocity of 54 mph?

Instead of the wishy-washy term "... within ...", let's assume that he reaches the final speed in 5 seconds,
so that we actually know when it was, and we can do math with it.
Average acceleration = (change in speed) divided by (time for the change)
54 mph / 5 sec = 10.8 miles per hour per second
If this rather ugly and unfamiliar unit makes you uncomfortable, the answer can be converted
into other units, which are exactly equivalent but more appealing:
-- 15.84 feet per second2
-- 38,880 miles per hour2
-- 4.828 meters per second2

Car is traveling at a constant speed of 12 m s when the driver accelarates the car reaches a speed of 26 m s in 6 s what is the average accelaration of the car?
The change in velocity is 26 m/s - 12 m/s = 14 m/s. The time taken for this change is 6 seconds. Therefore, the average acceleration is (change in velocity / time) = 14 m/s / 6 s = 2.33 m/s^2.
What is a real life example of negative acceleration?
A real-life example of negative acceleration is when a car slows down to a stop at a red light. As the driver applies the brakes, the car's velocity decreases, resulting in negative acceleration.
A sentence for negative acceleration?
Yes, negative acceleration is slowing down. Take the example of a car going from 0 to 60 mph this would be positive acceleration. If once it reaches 60 mph the foot is removed from the petal the car will continue to move but due to friction and wind resistance it will begin to slow down, while slowing down it is in negative acceleration.
What is a real life example of acceleration?
A car speeding up from a stop sign is a real life example of acceleration. As the driver presses on the gas pedal, the car's velocity increases over time, showing acceleration.
Can the velocity of an object be zero at the same instant its acceleration is not zero?
Consider the gravitational pull of the earth and acceleration due to gravity. When you throw a ball in the air, at the highest point, it is stopped and has a velocity of 0. However, if the acceleration of the ball was also 0, then the ball would not be able to come back down to the earth. In order for the ball to come back down, there must be an acceleration. This acceleration is the acceleration due to gravity which is constant at the surface of the earth at 9.8 m/s^2. Another example: Say a car is rolling down a hill backwards. In order to stop the car from rolling more, the driver accelerates. After a certain amount of time, the car will stop (with velocity of 0) and then it will start moving up the hill again. When it is stopped, the car is still accelerating in order to overcome the force of gravity pulling the car down the hill.Technically, an object is accelerating if it's changing it's velocity. This includes speeding up, slowing down, and turning. So, yeah, if an object isn't moving at all, but is turning, it's still accelerrating.
A driver starts his parked car and within 5 seconds reaches a velocity of 54 km per hour as he travels east what is his acceleration?
vf=54 km/hr vi=0km/hr t=5sec/0.001hr a=5400 km/hr 54km/hr- 0km/hr --------------------- 0.001 hr

A dragster started from rest and covered the flying 400m in 3.8s. It reached a final speed of 210m per s.Calculate the average acceleration?
The final velocity is 210 m/s, initial velocity is 0 m/s, and the time taken is 3.8 seconds. Using the formula for acceleration, a = (v_f - v_i) / t, the average acceleration is (210 - 0) / 3.8 = 55.26 m/s^2.
What is an example of acceleration in direction of motion?
An example of acceleration in the direction of motion is when a car speeds up while driving on a highway. As the driver presses on the accelerator pedal, the car's velocity increases in the same direction as its motion, resulting in acceleration in the direction of travel.
How does positive and negative acceleration affect motion?
positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.
