A car travels 3.0km due south and then 4.0km due west.what is it displacement from the starting point.
R^2=A^2 B^2
am not sure if dat is the formula please help me
dat no de fomla
R^2 = A^2 + B^2
Surely you could have looked that up in less time than posting here and waiting for a response...
Can you show the working

To find the displacement from the starting point, you can use the Pythagorean theorem, which states that the square of the hypotenuse (c) of a right triangle is equal to the sum of the squares of the other two sides (a and b).
In this case, the car has traveled 3.0 km south and 4.0 km west, forming a right triangle. The 3.0 km south corresponds to the "opposite side" (b), and the 4.0 km west corresponds to the "adjacent side" (a). Therefore, you can use the Pythagorean theorem to find the displacement (c) as follows:
c² = a² + b²
Substituting the values:
c² = 4.0² + 3.0²
c² = 16.0 + 9.0
c² = 25.0
So, the displacement (c) squared is equal to 25.0. To find the actual displacement, you need to take the square root of both sides:
c = √25.0
Taking the square root of 25.0 gives us:
c ≈ 5.0 km
Therefore, the displacement from the starting point is approximately 5.0 km.
