A crate of books is dragged horizontally across a rought floor at a constant velocity. If the normal force acting on the crate is 66 Newtons, determine the
mass of the crate.

m = 6.73 kg

Explanation:

Given that,

The normal force acting on the crate = 66 N

We need to find the mass of the crate.

Normal force = weight of the crate

N = mg

m is mass of the crate

So, the mass of the carte is 6.73 kg.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500
