Answer:
These are called kinematics equations.
Explanation:
These equations are used when there is either a constant velocity motion or a constant acceleration motion.
The direction of the friction force F exerted by the horizontal surface on the crate will be in the left direction.
<h3>How to depict the force?</h3>
From the information given, the 85-lb force P is applied to the 200-lb crate, which is stationary before the force is applied.
mg = 200 × 0.2248 × 9.8 = 440.608
The static friction force will be:
= 0.5 × 440.608
= 220.304N
Therefore, the static friction is greater than the force applied. Therefore, there'll be a static friction acting on the box on the left direction.

Answer:
I believe it would be Direction B
Explanation:
After passing A, gravity would pull the ball downwards
To convert between mass<span> and </span>number of moles, you can use themolar mass<span> of the substance. Then, you can use Avogadro's</span>number<span> to convert the </span>number of moles<span> to </span>number<span> of atoms.</span>
