Question

A golfer takes two strokes to get his ball into the hole.
The first stroke displaces the ball 40m north and sec-
ond stroke 50m at tan-'(4/3) to the south of east.
The displacement needed to get the ball into the hole
on the first stroke is​

Answer 1

Answer:

hope it helped ya mate

Step-by-step explanation:

displacement

= (0,12) + 6(cos45°, -sin45°) + 3(-cos45°, -sin45°)

= (0,12) + (6/√2, -6/√2) + (-3/√2, -3/√2)

= (3/√2 , (12√2-9)/√2 )

= appr (2.12 , 5.64)

magnitude = 6.02

angle with x-axis:

tan Ø = 5.64/2.12

Ø ≐ 69.4°
