Answer:
The acceleration of the car is [tex]2.68\ m/s^2[/tex].
Explanation:
Given that,
Initial speed of the car, u = 50 mph
Since, 1 mph = 0.44704 m/s
u = 22.35 m/s
Final speed of the car, v = 80 mph = 35.76 m/s
Time, t = 5 s
To find,
The acceleration of car.
Solution,
The rate of change of velocity of an object is equal to its acceleration. Its formula is given by :
[tex]a=\dfrac{v-u}{t}[/tex]
[tex]a=\dfrac{35.76-22.35}{5}[/tex]
[tex]a=2.68\ m/s^2[/tex]
So, the acceleration of the car is [tex]2.68\ m/s^2[/tex].
The acceleration of the car is 6m/h^2
Data given;
- Initial velocity = 50mph
- final velocity = 80mph
- Time = 5 seconds
Acceleration
To calculate the acceleration of the car, we have to use the formula
[tex]a = \frac{\delta v}{t}[/tex]
where the velocity and time taken are;
[tex]u = 50mph\\\\v = 80mph\\t = 5s\\[/tex]
The acceleration of the car is given as
[tex]a = \frac{80-50}{5}\\ a = \frac{30}{5}\\ a = 6m/h^2[/tex]
From the calculations above, the acceleration of the car is 6m/h^2
