Question

two kids are playing with a beach ball at the beach, and the ball floats in the water between them. the balls velocity has an x-component of 1.0 miles per hour and a y-component of -2.5 miles per hour. suddenly, a gust of wind causes the balls velocity to change. the change in the balls velocity has an x-component of 1.4 miles per hour and a y-component of 7.6 miles per hour.
what is the balls resultant velocity?
the balls resultant velocity has an x-component of □ miles per hour and a y-component of □ miles per hour.

Explanation:

Step1: Calculate resultant x-component

Add initial x-velocity and x-change:
$v_x = 1.0 + 1.4$

Step2: Calculate resultant y-component

Add initial y-velocity and y-change:
$v_y = -2.5 + 7.6$

Answer:

The ball's resultant velocity has an x-component of $2.4$ miles per hour and a y-component of $5.1$ miles per hour.
