B the desert was once covered in water
The answer is option C .Because as the direction of the boy changes ;velocity changes .
The three kinematic equations provided by Newton explain or determine the acceleration of the stone after it departs the ramp.
<h3>What is acceleration?</h3>
The rate of velocity change concerning time is known as acceleration.
There are three kinematic equations used to find the acceleration depending upon the perameters;
1.
2.
3.
The acceleration of the marble after it leaves the ramp is described or found by the three kinematic equations given by Newton.
Hence there are three kinematic equations to support your discussion.

Answer:
the total force vector, on test charge is points from origin to point C( 1, 1 )
Explanation:
Given the data in the question, as illustrated in the image below;
from the Image, OA = 1, OB = AC = 1
so using Pythagoras theorem
a² = b² + c²
a = √( b² + c² )
so
OC = √( OB² + AC² )
we substitute
OC = √( OA² + AC² )
OC = √( 1² + 1² )
OC = √( 1 + 1 )
OC = √2
Coordinate of C( 1, 1 )
Hence, the total force vector, on test charge is points from origin to point C( 1, 1 )
Ah hah ! Thank you for that data at the end ... about the 2.5kg box.
I thought we were going to have to calculate it from Square-1.
Without checking, I'll assume that a 2.5kg box at that location really
does weigh 6.1 Newtons.
Weight (gravitational force) is directly proportional to the mass of
the object ... if you eat twice as much, you'll weigh twice as much.
So the weight of the 1kg box is
(1 / 2.5) x (6.1 N) = 2.44 Newtons .
