Question

The ball was kicked in the air and it iss about to hit the . if horizonta componenet of its final velocity is 10m/s and vertical component of its final velocity is -10m/s .what is the magnotide of th final vellocity of the ball?

Answer 1

The magnitude of the final velocity is 14.14 m/s

Step-by-step explanation:

The horizontal component of the final velocity and vertical component of the final velocity, forms a perpendicular vector. To determine the magnitude of the final velocity, we sum the two vectors.

To add two perpendicular vector, Pythagoras principle is used.

`V^2 = V_x^2 +V_y^2\\\\V = √(V_x^2 +V_y^2)\\\\V = √((10)^2 +(-10)^2) =14.14 m/s`

The magnitude of the final velocity is 14.14 m/s
