Question

A ball is thrown so that its initial vertical and horizontal components of velocity are 40 m/s and 20 m/s, respectively. Find the initial speed of the ball.

Answer 1

Step-by-step explanation:

The x and the y components are the legs of a right triangle....you want to find the hypotenuse, just use the Pythagorean theorem

speed^2 = 40^2 + 20 ^2

speed = 44.72 m/s
