Help me pleassseee If a Teflon box with a weight of 35N is pushed across a steel floor with a force of 8.2N, what is the acceleration of the box?

I know the answer is 1.9 m/s
But I don’t know how to get there or like show my answer

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

Apossible explanation for a set of facts that can be tested by further investigation is called

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. when the carts collide, they hook together. assume that positive momentum is to the right. which graph best represents the momentum of both carts over time, before and after the collision?
