The magnitude of the friction on the cart is 28,56 N
To measure the deceleration of a car, without the value of the time of the movement, the <u>Torricelli equation</u> is used, which consists of:
Where is final velocity, is initial velocity, is acceleration, and is displacement.
Now, substitute the values in the formula:
Finally, the value of the acceleration found is multiplied by the mass of the object, thus measuring the friction force:
