PLEASE HELP ME I NEED THIS ASAP! In an experiment, a student measures the speed of a toy car in locations K through N as it rolls down a ramp. Based on the data collected in the table, a conclusion was drawn by the student that unbalanced forces acting on the toy car affect its average speed. What reasoning led to the interpretation of this data and conclusion?

A) The average speed of the car decreases as distance traveled increases.
B) The average speed of the car increases as distance traveled increases.
C) The average speed of the car increases as the force of gravity decreases.
D) The average speed of the car decreases as the force of gravity increases.

Total pressure= 120945[Pa]

Force exerted = 29026800 [N] or 29.02*10^6 [N]

Explanation:

We know that the total pressure is the result of the sum of the atmospheric pressure plus the manometric pressure. The equation is:

In this problem we know the atmospheric pressure 101.325x10^3 [Pa], therefore we need to find the manometric pressure.

The manometric pressure in the bottom of the swimming pool depends only on the water column of water generated (depth of the swimming pool)

where:

density = density of the water 1000 [kg/m^3]

g= gravity [m/s^2]

h= column of water (meters)

replacing the values:

The total pressure will be:

The force exerte on the bottom is defined by the following expression:
