To calculate acceleration, use the formula (a = \frac{\Delta v}{\Delta t}), where (\Delta v) is the change in velocity and (\Delta t) is the time taken. Here, the change in velocity ((\Delta v)) is (40 , \text{mph} - 60 , \text{mph} = -20 , \text{mph}). Over 5 seconds, the acceleration is (a = \frac{-20 , \text{mph}}{5 , \text{s}} = -4 , \text{mph/s}). Thus, the object has an acceleration of (-4 , \text{mph/s}), indicating a deceleration.
It goes from 0 mph to 80 mph in 1.8 seconds Acceleration = change in speed/time taken = (80 - 0)/1.8 mph per second = 44.4 mph per sec
To calculate the acceleration of a car that changes its speed from an initial velocity (Vi) to a final velocity (Vf) over a time period (t), you can use the formula: ( a = \frac{Vf - Vi}{t} ). First, convert the speeds from mph to a consistent unit like feet per second or meters per second if necessary. Then, substitute the values into the formula. For example, if a car accelerates from 0 mph to 60 mph in 4.5 seconds, its acceleration would be approximately ( 2.67 , \text{mph/s} ).

The car accelerates an average of 7.5 mph per second. It increases its speed 7.5 mph for every second that it accelerates. The car accelerated from zero to 60 mph in 8 seconds. If we wish to find out how fast it accelerated, we need to divide its acceleration (final speed minus initial speed) by the amount of time that it took to get going that fast. In this case, 60 divided by 8 equals the answer 7.5 mph/sec.
The formula for finding time based on acceleration and speed is: (Delta)t = (Delta)v/a Change in time = change in speed / acceleration t = 75-15 / 20 t = 60 / 20 t = 3 seconds

It goes from 0 mph to 80 mph in 1.8 seconds Acceleration = change in speed/time taken = (80 - 0)/1.8 mph per second = 44.4 mph per sec
To find the acceleration, we can use the formula: acceleration = (final speed - initial speed) / time. Mike's car accelerates from 0 mph to 60 mph in 5 seconds, so the acceleration is (60 mph - 0 mph) / 5 seconds = 12 mph per second. Therefore, the acceleration of Mike's car is 12 miles per hour per second.
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph

Acceleration = Change in speed/Time Time = Change in Speed/Acceleration = 65mph/20mph per s = 65/20 seconds = 3.25 seconds
55/6 = 9.16666...mph/s
The car accelerates an average of 7.5 mph per second. It increases its speed 7.5 mph for every second that it accelerates. The car accelerated from zero to 60 mph in 8 seconds. If we wish to find out how fast it accelerated, we need to divide its acceleration (final speed minus initial speed) by the amount of time that it took to get going that fast. In this case, 60 divided by 8 equals the answer 7.5 mph/sec.
To calculate acceleration in miles per hour per second, first convert the acceleration from 0 to 60 mph in 3 seconds to miles per hour. 60 mph / 3 sec = 20 mph/sec. So, the acceleration in miles per hour per second is 20 mph/sec.
Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.
