Explanation:
The static pressure is P = ρgh, where ρ is the density of the fluid and h is the depth.
For the first person:
P = (1000 kg/m³) (9.8 m/s²) (2.3 m)
P = 22,500 Pa
For the second person:
P = (1000 kg/m³) (9.8 m/s²) (3 m)
P = 29,400 Pa

Answer:
Only a backward force is acting, no forward force.
Explanation:
- Once released from the initial push, in absence of friction, the shopping cart would continue moving forward at a constant speed forever.
- As it would move at a constant speed, no net force would be acting on it.
- So, if it is gradually slowing, there must be a net force producing an acceleration in a direction opposite to the movement.
- This force is the kinetic friction force, and is the only force acting on the cart in the horizontal direction.
- As any friction force, opposes to the relative movement between the cart and the horizontal floor, which means that is directed backward.
- This is consistent with the direction of the acceleration of the cart.
-- Multiply each side of the formula by 2
-- Then divide each side by t
-- Then subtract V(i) from each side.
