To calculate the magnitude of acceleration, we can use the equation:
acceleration = change in velocity / time
In this case, the car starts from rest, so its initial velocity is 0 m/s. The distance covered in 10s is 40m. Therefore, we need to find the final velocity.
The distance covered can be calculated using the equation:
distance = initial velocity * time + (1/2) * acceleration * time^2
Since the car starts from rest, the equation reduces to:
40m = 0 * 10s + (1/2) * acceleration * (10s)^2
Simplifying the equation, we get:
40m = (1/2) * acceleration * 100s^2
Dividing both sides of the equation by 100s^2, we get:
0.4m/s^2 = acceleration
Therefore, the magnitude of the car's acceleration is 0.4 m/s^2.
A car starts from rest and covers a distance of 40m in 10s . Calculate the magnitude of its acceleration.
