If each washer has a mass of 4.9 g, then the mass of two washers in kilograms would be Given that F = ma, and if 4 washers are attached to the string and car instead of 2, then the applied force on the car will be

Given that,

Mass of each washer  = 4.9 g

We need to calculate the mass of two washers in kg

Using conversion of unit

Mass of each washer

So, Mass of two washers is

Put the value of m

If 4 washer are attached to the spring

We need to calculate the applied force on the car

Using formula of force

Put the value into the formula

Hence, (i), The mass of two washers is 0.0098 kg.

(ii). The applied force on the car is 0.192 N.
