Emily passes a soccer ball 6.0 m directly across the field to kara. kara then kicks the ball 14.5 m directly down the field to luisa. what is the ball's total displacement as it travels between emily and luisa?

Below is the solution:

et the position of emily be a

let the position of kara be b

let the position of luisa be c

abc is a right angled triangle, at b

displacement = ac

ac = root of ab^2 + bc^2 (pythagoras theorem)

= root of 6^2 + 14.5^2

= root of 246.25

= 15.69
