a body starting from rest attains a speed of 8 m/s in 2 seconds. find the acceleration of the car.
Use formula v=u+a*t, 8=0+ a*2.....a=4 m\sec2
To find the acceleration of the car, you can use the formula:
acceleration = (final velocity - initial velocity) / time
In this case, the final velocity is 8 m/s, the initial velocity is 0 m/s (since the car starts from rest), and the time is 2 seconds. Plugging these values into the formula:
acceleration = (8 m/s - 0 m/s) / 2 s
Simplifying the equation gives:
acceleration = 8 m/s / 2 s
Dividing 8 by 2 gives:
acceleration = 4 m/s²
Therefore, the acceleration of the car is 4 meters per second squared.
