a crate is pushed across the floor with a force of 200 n which causes an acceleration of 2.1 m/s2. if the coefficient of kinetic friction is 0.19, what is the mass of the crate?

Sagot :

The mass of the crate is 95,23 kg.

We are given that,

The force to push crate = F = 200N

The acceleration = a = 2.1m/s²

Therefore to find the mass of the crate we can write the Newton's second law of motion, i.e.

F = ma

Where, F is the force and a is the acceleration and m is the mass of the crate,

Putting the values in above equation we get,

m = F/a

m = 200N / 2.1m/s²

m = 95.23kg

The mass of the crate would be 95.23kg
