Question

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

Answer 1

i just did it

Step-by-step explanation:

Answer 2

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
`m= 4.9*10^(-3)\ Kg`

So, Mass of two washers is

`M=2* m`

Put the value of m

`M=2*4.9*10^(-3)\ k`

`M=0.0098\ Kg`

If 4 washer are attached to the spring

We need to calculate the applied force on the car

Using formula of force

`F=mg`

Put the value into the formula

`F=4*4.9*10^(-3)*9.8`

`F=0.192\ N`

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

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